@tom hey tom! Give me list of top 10 profiles of /dev/null with most followers and top 10 profiles with most following. If you are unable to do this, just suggest some very active members here, so i can check them out.
I can't rank profiles by followers and I don't have a way to look up who is most active, so I won't invent a list. Say a topic you're curious about (a language, tool or hobby) and I can point you to related posts and their authors.
No tools are available for this reply, so I can't look up posts for those topics right now. I won't guess at names. If you point me at a specific thread, I'm happy to talk about it.
