Bluesky out-talks Hacker News

Across 48 developer tools, Bluesky logged 638 relevant mentions a day and Hacker News logged 227. Before cleanup, that looks like nearly 3x. Status-page relays, job boards, trending-repo feeds and accounts that repost Hacker News made up 33% of Bluesky's volume, so we removed them. People alone still posted 430 relevant mentions a day.

The two rooms talk differently. 82% of Hacker News mentions are comments under a story, so the talk clusters around the links that reach the front page. On Bluesky, 74% of what people post are standalone posts, not replies.

We counted posts, not readers. One Hacker News front-page thread can reach more people than hundreds of Bluesky posts, so this measures how much developers talk, and says nothing about influence. Depending on how strictly we define a bot, the ratio lands from 1.9x to 2.1x.

Is Stack Overflow dead? As a place to ask new questions, close to it. Developers asked 186,031 questions there in October 2015 and 968 in October 2026. The best month on record was March 2014, with 207,169.

The slide began years before AI chat tools. October counts fell 43% between 2015 and 2022. The fall sped up after ChatGPT launched in November 2022: down 51% in 2023, 56% in 2024, 77% in 2025 and 82% in 2026. We can show the timing, and this data can't prove the cause.

Our month of tracking agrees. Across 48 tools we logged about 9 Stack Overflow keyword matches a day, out of 15,408 across every platform. The archive stays online, and we didn't measure how many people still read it.

Developers still ask about their tools in public. We tagged 21% of relevant mentions as a product question, and almost none of them were on Stack Overflow.

A GitHub issue goes to the maintainers. A post on X goes to whoever follows you. Neither builds the shared archive of answers that Stack Overflow did.

We can't see the questions people ask ChatGPT or Claude. Those stay private, so this chart only covers questions asked in public.

Three platforms hold most of the conversation about developer tools. GitHub issues and X are nearly level, and Reddit follows. Collection hit its limit on the biggest tools, so treat these shares as estimates.

Bluesky comes fourth. Even with its bots removed, it carries more than Hacker News, TikTok, DEV and LinkedIn combined (362 a day). We only measured automation on Bluesky and Hacker News, so this chart shows every platform before bot removal.

We removed bug reports before comparing platforms, because a bug report reads as negative by nature. Hacker News comes out as the harshest place to get discussed, and Reddit is about as positive as X (41% against 42%).

GitHub issues show why the adjustment matters. With bug reports included, 26% of GitHub mentions are negative. Without them, 7% are, and 83% are neutral working conversation.

TikTok is the friendliest platform, at 55% positive. It stays at 51% after we remove promotional posts.

Developers talk about frameworks and databases more warmly than anything else we tracked. Observability and analytics tools sit close to even, at +2.

Hosting draws the most complaints, with 24% of mentions negative. We publish these numbers by category and never rank single tools.

We logged 15,408 keyword matches a day across the 48 tools. 4,959 of them were about the tool.

The name decides most of it. Clerk, Linear, Neon and Render all land under 10%, because people use those words for other things every day. Claude Code reaches 74% and Datadog 70%. No invented name fell below 20%.

Octolens AI made these relevance calls, so the rates reflect how our classifier reads each post.

We looked at the 42 tools outside AI coding: databases, payments, hosting, observability and the rest. About a third of their mentions also bring up AI, agents or a model by name. Passing references count.

An LLM labeled a random sample of 600 of these mentions, and we reviewed the hard cases by hand. Posts that bring up AI read warmer, at 32% positive against 21%.

Six of the 48 tools are AI coding tools. Together they take 22% of all relevant conversation.

Claude Code and Cursor lead the list by a clear margin. Most other top pairs are stacks people build on together: Next.js with Vercel, Supabase with Vercel, Next.js with Supabase.

Direct rivals appear lower down, such as Datadog with Grafana and Lovable with Replit.
