Hachyderm
Large Mastodon server aimed at tech folks; explore page.
Hachyderm is one of the largest Mastodon servers, founded for and popular with hackers, scientists, and tech-sector folks (it’s where much of the 2022 Twitter exodus of AI/ML people landed). The linked page is its public explore view — trending posts, hashtags, and links across the server. A good starting point for following the fediverse’s technical crowd; like any Mastodon instance you can browse logged-out and interact from any server.
