What is Lemmy?
|List of instances||fediverse.observer|
Lemmy is a link-aggregator and the Fediverse's replacement for Reddit.
What does Lemmy feel like?
Lemmy is similar to sites like Reddit, Lobste.rs or Hacker News: You subscribe to communities that you're interested in, post links and discussions and vote and comment on them.
Communities are similar to forum categories, so Lemmy can be used as a forum.
Since it's part of the Fediverse different Lemmy instances can communicate with each other. Mastodon users can also take part in Lemmy discussions and subscribe to lemmy communities.
