Although Lemmy's userbase is quite large,it still is small enough that I do often see the same people in comment sections. It feels though, that I should recognise more names, because I can only remember around 5 individual ones.
You can't miss Will or Blaze. And onlinepersona@programming.dev because his signature is massive.
If I mention all the people I regularly talk to, I'll be here all day. It's a good varied bunch. I like that I'm forever hopping around and talking in different circles.
