Does anybody have a list of communities to add?

I'm sorry, is this the place to ask? Are they just called "communities"? Not sub...lemmys?

I wanted to curate something like old-Reddit for my front-page but I'm having trouble finding any sidebar lists of related communities. Do I just have to search and add each one individually if they're here? Does it matter if it's 'local' or 'all'?

I'm using Connect for the moment. Thanks in advance!

EDIT - you guys are awesome!
