I personally love !dadjokes@lemmy.world

I may be a little biased because I mod it ;)

You mean “sublemmy”? :)

For me, that would be oldweb@lemmy.ml. A lovely collection of old-school, hand-crafted personal websites full of creativity. Just for fun, not for profit.

I’ve found books@lemmy.ml to be fairly popular, and lived the Reddit sub. So I’m happy about that.
