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
I'd recommend visiting it or joining an instance that federates with it at least. The liberals like to make it out to be a communist propaganda machine but most of the content is memes, oss, and general left wing / anti-US stuff. They will ban you on some communities if you bring up tianemen square or uyghurs though, so that sucks, but otherwise most of the content / users on there are decent.
