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 !memes@lemmy.world if you like sciency posts mander.xyz has some excellent communities (communities=subreddits) like !science@mander.xyz and !biology@mander.xyz and for a meme science combo theres always the fantastic !science_memes@mander.xyz
You can also drop a shit(post) off at !lemmyshitpost@lemmy.world or hang out at !onehundredninetysix@lemmy.blahaj.zone (though you do have to post before you leave that one!)
There's much more around as well!
Obligatory, fuck Spez
There's even some instances with old reddit-like styling/formatting, if you're into that sort of thing.
I'll pimp my example: https://old.lemmy.fan/
https://oldsh.itjust.works/
Given the instance we are on: https://old.feddit.uk/
https://old.lemmy.world/
The Connect app is based off RiF. Best Lemmy app by far
i've only ever used https://old.lemmy.ca/
That works great on mobile!
Man Reddit really has something with that old UI. The new one runs like trash.
