Come one come all to the Lemmy-verse! It's nice and cozy here, we do have some "bad parts of town" but you can do an instance block and not deal with them lol
For your memes we have [email protected] if you like sciency posts mander.xyz has some excellent communities (communities=subreddits) like [email protected] and [email protected] and for a meme science combo theres always the fantastic [email protected]
You can also drop a shit(post) off at [email protected] or hang out at [email protected] (though you do have to post before you leave that one!)
There's much more around as well!
Obligatory, fuck Spez
You want lemmy.ml. They are obviously quite annoying, so many instances have defederated with them.
