Bluesky

The posting experience feels familiar to anyone who used Twitter: short posts, replies, reposts, follows. What sits underneath differs. Bluesky runs on the open AT Protocol, so servers can be self-hosted, other applications can be built against the same data, and your handle can be a domain you own. The feature creators notice first is custom feeds. In place of one algorithm you subscribe to feeds other people have built, which makes niche communities unusually easy to find. As a distribution channel it stays much smaller than X, so most creators hold a handle there and cross-post to it while running their main effort elsewhere.
