Bluesky just crossed 20M users

User growth, funding, and business model

• Bluesky reported crossing 20M users; some note this feels like a real inflection, with many large tech/infosec and journalism accounts recently arriving.
• Past funding (~$15M series A) is known; some wonder if the latest growth changes acquisition pressure or attracts suitors.
• Monetization discussed: past Namecheap handle deal (status now unclear), and a “Discord Nitro–style” paid-features model.

Bots, content quality, and signal-to-noise

• Compared to X, users report fewer bots and troll campaigns, especially around topics like Ukraine.
• Others find the discovery feed low quality, dominated by political chatter or off-topic posts despite selecting technical interests.
• Several say both Bluesky and X have poor signal-to-noise for serious discussion.

User experience vs Twitter/X and other platforms

• Many like that Bluesky “just looks like Twitter,” easing onboarding, and appreciate starter packs and custom feeds.
• Some claim tech and infosec timelines now rival pre-Elon Twitter for usefulness.
• Others bounce quickly, describing it as selfies, low-effort posts, and reaction content.
• Mastodon is framed as better for niche, blog-like use; Bluesky as the “central square” Twitter replacement.

Politics, echo chambers, and algorithms

• Multiple commenters see Bluesky as becoming a left-leaning counterpart to X/Truth Social, with a lot of anti-Musk/Trump content.
• Some find this exhausting and seek “apolitical” or more intellectual spaces; others argue that trying to remove politics is itself problematic or parochial.
• The default algorithm is criticized for quickly reinforcing narrow interests and polarization, though custom algorithms/feeds are seen as a partial antidote.

Decentralization, openness, and control

• Supporters emphasize open data, user-owned “personal data stores,” third-party feeds, moderation services, and the idea the network can outlast the company.
• Skeptics reply that Bluesky is still a company-controlled, centralized service in practice; the more advanced decentralized pieces are early and resource-intensive.

Moderation and censorship concerns

• Some praise stronger tools: shared blocklists, removing one’s posts from hostile quote-posts, and richer controls than X.
• Others worry about algorithmic bans and viewpoint-based removals, seeing a gap between the promise of user-controlled moderation and current centralized decisions.

Broader skepticism and alternatives

• Several warn about eventual “enshittification” and note prior waves of chat/social platforms fading after ~10 years.
• Some argue the entire fast-scroll social model is broken and suggest newsletters and curated sources as a better way to follow fields like programming or AI.
• A few criticize repeated HN posts on Bluesky user counts as hype and “trying very hard to make this platform happen.”
