I recently signed up and didn’t know where to park myself. So I got accounts on both lemmy.world and beehaw.org.
From lemmy.world I’ve added to a few of the beehaw subs that I’m subscribed to there. But I can tell you I see different content in my lemmy.world feed.
Don’t know why. A delay in the content making it over from beehaw to lemmy? But my home feed certainly looks different in both (even subscribing as closely is I can to the same feeds).
So for now I’ll stick with both and see how the dust settles.
