Understanding Bluesky: More Than Just a Twitter Alternative

Bluesky is often misunderstood as merely a competitor to Twitter (now X), but its network represents a broader social ecosystem built on an open protocol. Recent criticism focusing on Bluesky's tone and user growth overlooks this wider, multifaceted reality.

In recent discussions, some have questioned whether Bluesky's expansion is slowing and whether its community tends to lean politically left, creating an echo chamber effect or lacking humor. Investor Mark Cuban, who supports an app built on Bluesky's protocol, voiced concerns about the increasing negativity in replies on Bluesky, suggesting that it drives users back to X.

Meanwhile, Elon Musk and X's CEO have used these critiques to promote their platform as the genuine "global town square," further intensifying the debate.

This characterization is predictable given that Bluesky's early adopters largely include users discontented with X's ownership changes and political shift. After the 2024 U.S. elections, Bluesky saw a significant influx of users fleeing X, reaching over 36 million registered users by mid-2025, boosted further by high-profile Democrat endorsements.

Bluesky’s Broader Social Ecosystem

However, Bluesky's social app is only one example of what's possible within the AT Protocol ecosystem. Users can explore different apps built on the same underlying technology to customize their social media experience. This ecosystem includes specialized social platforms like Blacksky, tailored for the Black online community, and Gander Social, targeting Canadian social media users.

Feed-building apps such as Graze and Surf empower users to curate their content preferences more finely, focusing on interests like sports or entertainment while filtering out less desired topics like politics. BlueSky and other clients provide options to select or combine default feeds based on user interests, making the experience highly personalizable.

The AT Protocol network extends beyond Bluesky itself, encompassing a diverse array of applications including photo and video sharing, live streaming, communication, blogging, music, and TV/movie recommendations. Other tools also aggregate content from multiple social networks and open protocols, blending feeds from Bluesky, Threads, Mastodon, and more.

Why it matters

Understanding Bluesky’s positioning signals a shift in social media towards decentralized and federated networking models. For startups and founders, this represents an opportunity to innovate around open protocols that break away from monolithic platforms, fostering more user empowerment and tailored social interactions.

Risks & opportunities

A key opportunity lies in building apps that cater to niche communities or specialized content within open ecosystems, enabling distinct user experiences. However, the risk exists that fragmented platforms may struggle with network effects and content moderation, as seen with previous niche social networks like Parler or Telepath.

Startup idea or application

A compelling startup idea would be a customizable social feed aggregator that leverages the AT Protocol to allow users to seamlessly combine and filter content from multiple decentralized social platforms. The app could employ AI to personalize feeds dynamically while enabling community governance features to maintain quality and reduce toxicity.
