It's kinda weird at first, but you'll get used to it.
I had people that followed me on reddit that now "follow" me on lemmy. It's obviously not possible to follow users here, but they'll go to my profile and scroll, which is close enough.
Lemmy is still small enough that anyone can fairly reliably start noticing other users over time and look forward to interactions, or their posts/comments, even without going through the extra step of looking them up.
It's both cool and disconcerting lol
