I gall into most of those categories.
That said, I still have a hard time dropping reddit until a network effect happens here or the multi-feddit stuff can start combining same-named subs across the fediverse.
I spent most of my time on Reddit looking at: various sports,cooking, finance (pf, investing, bogleheads), IT (sysadmin, vmware, homelab), gaming (console and PC and specific game subs), and PC hardware subs. (Plus some for sale places).
I wasn’t really one to do much OC, but would participate in comment threads fairly often. I think lemmy/fed has potential, but it’s going to need to be simpler for the average person to get logged in and just see the content they want with out jumping through a bunch of searches and hoops.
