:::
1. X
Audience Growth
X's mobile user base has seen a decline, dropping 15.2% year-over-year - from 132 million in June 2025 to 125 million daily active users by January 7, 2026 [2]. Despite this, its desktop traffic remains strong. When factoring in web traffic, X averages 145.8 million daily visits globally, far outpacing Threads' 6.9 million and Bluesky's 5.3 million [2]. This highlights X's continued dominance as a hub for desktop users seeking real-time news and public discussions, even as mobile engagement wanes.
Demographically, X retains a foothold among U.S. users. 26% of surveyed U.S. consumers visit X daily, compared to 18% for Threads and 14% for Bluesky [6]. Younger audiences are particularly engaged, with 33% of Gen Z and 37% of Millennials using the platform daily as of early 2025 [6]. However, experts caution that X is "barely holding on to its core audience" rather than expanding significantly [6]. These numbers emphasize the importance of crafting content strategies for X, Threads, and Bluesky that resonate with existing user bases.
Engagement Metrics
When it comes to engagement, X presents a mixed bag. The median engagement rate is 3.6%, notably lower than Threads' 6.25% [1]. Most posts see a median of just 4 interactions [3]. However, the platform's average engagement per post is 328 interactions, with a standard deviation exceeding 5,159 [3]. This wide range underscores X's unpredictable nature - while many posts struggle to gain traction, those that go viral can achieve unparalleled reach.
"X is the best platform for viral reach, even though posting there means you run the 'risk' of modest engagement." – Tamilore Oladipo, Sr. Content Creator, Buffer [3]
Platform Features
X's distinctive features set it apart from competitors. Its algorithm prioritizes real-time relevance and trending topics, making it a digital "town square" where breaking news, live events, and viral moments dominate [1][3]. Tools like quote tweets allow creators to amplify their reach by adding their own perspective to ongoing conversations, while threaded stories enable longer narratives without losing the platform's concise style.
To succeed on X, creators need to grab attention immediately. A strong hook that stops users mid-scroll is essential [1]. The platform rewards timeliness, shareability, and content tied to trending discussions or current events. Posts that align with these priorities are more likely to gain algorithmic visibility, making X an ideal space for creators who can react quickly and capitalize on the moment [1].
2. Threads
Audience Growth
Threads has seen explosive growth. By January 7, 2026, it reached 141.5 million daily active users on mobile, surpassing X's 125 million users [2]. This marks an impressive 127.8% year-over-year growth since June 2025 [2]. The platform now boasts 350 million monthly active users, with projections suggesting it could hit 400 million by the end of the year [2][7].
Thanks to Instagram's massive user base of over 2 billion, Threads onboarded 200 million new users between mid-2024 and mid-2025, outpacing X's growth by a factor of four during the same period [7][8]. Instagram users can seamlessly transition to Threads with their existing profiles and followers, avoiding the typical challenges new platforms face in building an audience from scratch.
Threads is especially popular among younger users. As of early 2025, 26% of Gen Z and 27% of Millennials use the platform daily [6]. On the other hand, only 2% of Boomers are daily users, reflecting Threads' mobile-first design and its appeal to a younger demographic [6].
Engagement Metrics
Threads' rapid growth is matched by its strong engagement. The platform boasts a median engagement rate of 6.25%, significantly higher than X's 3.6% [1][8]. In February 2025, the median Threads post received 5 interactions, surpassing X's 4 and Bluesky's 3 [3]. While the average Threads post garners 58 interactions, lower than X's 328, this difference is due to X's highly skewed data, where a small number of posts go viral while the majority see minimal engagement [3].
"Threads rewards creators who post regularly with steadier audience growth than any other platform." – Tamilore Oladipo, Sr. Content Creator, Buffer [3]
A standout example of Threads' potential comes from Sendible, a social media management platform. Between March and June 2025, they achieved a 30,000% increase in Threads views using their "REAL Threads framework", which focused on consistency and community engagement. Within three months, Threads became their top channel for brand awareness, bringing in 90,000 impressions [8].
Platform Features
Threads' design prioritizes meaningful interactions, setting it apart from other platforms. Its algorithm encourages posts that spark replies and discussions, making open-ended questions and thoughtful engagement key strategies for creators [3][1]. Unlike X, which focuses on breaking news and trending topics, Threads emphasizes building communities and fostering dialogue.
The platform’s mobile-first approach has been central to its success. While X still dominates web traffic with 145.8 million daily visits compared to Threads' 6.9 million [2], Threads leads in mobile usage, where most social media activity happens. This focus has helped Threads overtake X in daily active smartphone users [2].
In February 2026, Threads introduced "Dear Algo", an AI-driven feature that allows users to customize their feeds by typing "Dear Algo" in a post to request more or less of a specific topic. This adjustment lasts three days and is visible to others, who can share and apply the same filter to their own feeds [2].
Threads also supports 500-character posts and up to 10 photos per post [8], offering more creative flexibility than Bluesky's 300-character limit. (Compare these to real-time Bluesky stats for a full picture of current network activity.) Users can add one community-style tag per post to improve discoverability in niche topics [1]. The platform’s largest demographic - users aged 25 to 34 - makes it an excellent choice for brands targeting young professionals [8].
"If maximizing interactions per post is a priority for your brand, Threads is the platform to prioritize." – Tamilore Oladipo, Sr. Content Creator, Buffer [1]
3. Bluesky
Audience Growth
Bluesky's growth has been steady and event-driven, setting it apart from the rapid, viral trends often seen on other platforms. Between February 2024 and April 2025, the platform grew from 5 million users to 35 million [10]. By February 13, 2026, its user base reached 42,495,649, reflecting a 22.5% annual growth rate [11].
This growth pattern isn't fueled by massive spikes but rather by specific events. For instance, in August 2024, Bluesky saw a surge in UK signups following heated debates and controversies on X. However, its growth in the U.S. during July 2024 was more modest, with monthly active users increasing by just 1.8%, compared to Threads' 20% jump during the same period [4]. The platform resonates particularly well with younger audiences, including Gen Z and Millennials, who show higher daily engagement [6].
Engagement Metrics
When it comes to engagement, Bluesky favors steady, community-driven interactions over the viral spikes seen on platforms like X and Threads. In February 2025, the median post on Bluesky received 3 interactions, slightly below Threads' 5 and X's 4. However, its average engagement of 21 interactions is more consistent, with a much lower standard deviation (279) compared to Threads (628) and X (5,159) [3].
"Growth on Bluesky is slower but steadier, making it better suited for niche, community-driven content rather than viral reach." – Tamilore Oladipo, Sr. Content Creator, Buffer [3]
This consistency highlights Bluesky's focus on fostering meaningful connections rather than chasing virality.
User Retention
Bluesky emphasizes building and maintaining niche communities, but it faces challenges in user retention. The platform experiences a -12.9% monthly momentum dip, though weekly growth shows a 3.4% increase, indicating some stabilization efforts. As of February 2026, Bluesky identified 110,752 bots, and only 0.016% of users (6,836 total) have blue checkmarks, verified through trusted domains like The New York Times or Microsoft [11].
Platform Features
One of Bluesky's standout features is its focus on decentralization and user autonomy. Users and organizations can use their own web domains as handles, such as @wfp.org or @rug.nl, creating a built-in verification system that sidesteps paid badges [9]. Tools like Bluesky Analytics and Bluesky Network Statistics allow creators to monitor growth and engagement in real time.
Bluesky's algorithm prioritizes posts that encourage discussions and long-term connections rather than chasing viral content. This makes it an ideal space for creators targeting niche audiences who value meaningful, consistent engagement. By early 2026, the platform was adding approximately 0.41 new users per second, showcasing its gradual but steady expansion [9].
These features underscore how Bluesky is carving out a space for creators who value deeper community interactions, positioning the platform as a unique alternative in the social media landscape.

Advantages and Disadvantages
Let's break down the key strengths and challenges of these platforms to better understand how they shape content strategies.
Each platform is unique, with its own algorithms, user behaviors, and engagement trends. Knowing these trade-offs can help you make smarter decisions about where to focus your efforts.
X stands out as the go-to for viral reach, boasting an average of 328 interactions per post [3]. But here's the catch: engagement is wildly inconsistent. With a standard deviation of 5,159 [3], the majority of posts receive minimal attention, while a lucky few go viral. As Tamilore Oladipo, Sr. Content Creator at Buffer, explains:
"X is the best platform for viral reach, even though posting there means you run the 'risk' of modest engagement" [3].
Adding to the challenge, X has been losing steam in user retention. By June 2025, mobile daily active users dropped 15.2% year-over-year, leaving the platform with 132 million daily users [2].
Threads, on the other hand, shines with consistent and predictable growth. Its median engagement rate of 6.25% is 73.6% higher than X's 3.6% [1]. The engagement spread is much narrower at just 628 [3], making it a more stable option. By January 7, 2026, Threads had surpassed X with 141.5 million mobile daily active users [2]. However, its web presence is a weak spot, with only 6.9 million average daily visits, far behind X's 145.8 million [2].
Bluesky is all about predictable engagement, featuring the lowest spread at just 279 [3]. It’s perfect for niche communities, though its scale remains modest. By June 2025, daily active users grew by 372.5% year-over-year, but the platform still sees only 5.3 million average daily visits [2]. Bluesky excels at fostering meaningful, community-driven discussions, even if it struggles to reach a broader audience.
"Bluesky isn't about mass engagement - it's about focused, community-driven content", Oladipo points out [3].
| Platform | Primary Strength | Primary Weakness | Growth Style |
|---|---|---|---|
| X | Extreme viral reach [3] | High inconsistency; declining users [2][3] | Volatile/Event-driven [4] |
| Threads | High engagement rates [1] | Weak web presence [2] | Consistent/Predictable [3] |
| Bluesky | Niche community focus [3] | Smallest user base [4] | Slow/Steady [3] |
This breakdown highlights why a tailored, cross-platform strategy is essential. Tools like TheBlue.social's cross-posting scheduler help you optimize content to fit each platform's unique strengths and challenges.
Conclusion
When it comes to choosing the right platform, it all boils down to your specific goals. Each platform brings something different to the table, making it essential to align your strategy with their unique strengths.
X is perfect for those seeking viral reach and quick visibility. With 125 million daily active users on mobile [2], it remains a hub for timely content. However, its engagement tends to be unpredictable - posts can either gain massive traction or go unnoticed [5].
For steady and reliable growth, Threads stands out. With 141.5 million mobile daily active users and a median engagement rate of 6.25% [1], Threads rewards consistency and meaningful interactions. Unlike X, it offers a more stable environment for fostering engagement over time.
On the other hand, Bluesky caters to a niche audience. With an impressive year-over-year growth rate of 372.5% [5] and the lowest engagement variability at just 279 [3], it’s the go-to platform for creating close-knit communities centered around specific topics or industries.
A smart approach involves using all three strategically. Each platform plays a role in a balanced social media strategy. Tools like TheBlue.social's cross-posting scheduler make it easy to adapt your content - whether you’re crafting viral posts for X, sparking conversations on Threads, or sharing targeted insights on Bluesky - all from one place.
To get the most out of your efforts, align your platform choices with your goals and track performance. Resources like Bluesky Network Statistics can help you measure which platforms are delivering the results that matter most to your objectives.
