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.
Dumb question i can't find an answer to: You see a post in a different Lemmy server than your own, and if you try to answer it says you're not logged in, because you're not in that server. How do i see posts/communities through your server so that i can vote or comment? Don't see a clear answer to this in the docs, or have missed it completely.
Edit: Partially answering myself: Go to the "search" box of your instance and put the name of the community you want in the format "!linux@lemmy.ml", it should show you that community through your server. Will update if/when i find an answer for direct posts that does the same.
Its the same for posts or comments, you need to paste the url in the search bar of your instance. For this you should copy the url from the colorful fedilink icon.
