We are happy to see that many of you are exploring Lemmy after Reddit announced changes to its API policy. I maintain this project alongside @dessalines@lemmy.ml.
Lemmy is similar to Reddit in many ways, but there is also a major difference: Its not only a single website, but consists of many different websites which are interconnected through federation. This is achieved with the ActivityPub protocol which is also used by Mastodon. It means that you can sign up on any Lemmy instance to interact with users and communities on other instances. The project website has a list of instances which all have their own rules and administrators. We recommend that you sign up on one of them, to avoid overt centralization on lemmy.ml.
Another difference compared to Reddit is that Lemmy is open source, and not funded by any company. For this reason it relies on volunteer work to make the project better, whether it's programming, design, documentation, translating, reporting issues or others. See the contributing guide to get started. You can also donate to support development.
We also recommend that you read the documentation. It explains how Lemmy works and how to setup your own Lemmy instance. Running an instance gives you full control over the rules and moderation, and prevents us developers from having any influence. Especially large communities that want to use Lemmy should host their own instance, because existing Lemmy instances would easily be overwhelmed by a large number of new users.
Enjoy your time here! If you have any questions, feel free to ask below or in the Matrix chat.
I don't quite get it. How do you see posts from communities residing on other instances?
Swap from "Local" view to "All". It's on the top of the web page and in a menu top-left on Jerboa.
Are communities unique? e.g. could you have a !gaming community on Lemmy.ml but have another !gaming community with different content on another server?
Yes, that can absolutely happen. In fact, that exact situation is happening right now with !gaming@beehaw.org and !gaming@lemmy.ml
Not really an issue if you subscribe to both though.
In the longer term, I fully expect duplicate communities like that to resolve themselves with people predominantly using one over the other. EDIT: Or another possibility is that they might end up different due to moderation and rules (i.e: one is the memey gaming community and the other is the more serious one)
