Lemmy is similar to sites like Reddit, Lobste.rs, or Hacker News: you subscribe to forums you're interested in, post links and discussions, then vote, and comment on them. Behind the scenes, it is very different; anyone can easily run a server, and all these servers are federated (think email), and connected to the same universe, called the Fediverse.
For a link aggregator, this means a user registered on one server can subscribe to forums on any other server, and can have discussions with users registered elsewhere.
The overall goal is to create an easily self-hostable, decentralized alternative to Reddit and other link aggregators, outside of their corporate control and meddling.
Each Lemmy server can set its own moderation policy; appointing site-wide admins, and community moderators to keep out the trolls, and foster a healthy, non-toxic environment where all can feel comfortable contributing.

Comments and Reviews
Lightweight interface that is fast like lightning as well as open source and federated. What is there not to love?
Probably the most well developed open source reddit alternative, with features added constantly.
reading posts incrementally is still too hard unlike reddit with reddit enhancement suite (which has a few other nice features that lemmy does not have yet).
Cool application but the user base sucks
indeed. full of radical commie.
Lemmy is just as fun and interactive as Reddit, but with better privacy and less trolls.
Federated alternative to Reddit
Documentation is non-existent; provided installation method doesn't work out of the box. Pathetic.
Great website with a great community, and it is the best Reddit alternative I found. The community is still small, but if you join, you'll find yourself enjoying the warm community feel. Site is very fast and simple to use as well.
