In my short time on Kbin vs. Lemmy, the communities seem quite different already. Kbin reminds me of Reddit today: lots of one line answers and sarcasm, some rude comments too. Lemmy (and Beehaw) so far seem more genuine with more thorough discussions and feels like Reddit did 10 years ago.
Seeing this from the Jerboa app on Android, the instance source is very clear on the post. Posts from my instance don’t have the @instance attached so that’s how I know.
