I’d start these myself, but don’t have the time to moderate them.
Out of the Loop: Lemmings request to be updated on recent news, trends, and similar
ELI5: A community where Leminnings can request that complex ideas/knowledge it explained in layperson terms (not actually 5 y/o level tho)
BestOfLemmy: A community in which Lemmings cross-post the best posts & comments on Lemmy
AskScience: A place where Lemmings can ask science-related questions and relevant discussions.
They are both link aggregators. With kbin you can follow, post all of Lemmy without registering on a Lemmy instance.
Kbin also integrates easy with mastodon and show’s the microblog in the same way as if it was a Lemmy thread.
I registered on Lemmy and on kbin checking both out . I like kbin more for now but keep my options open.
