Twitter - This is where I'm the most active; I post art or game clips here sometimes.
Furaffinity - Art gallery, though it's pretty out of date right now. I've been neglecting this site quite a bit...
Fediverse - I run a single-user GoToSocial instance, which is compatible with Mastodon but lighter on system resources.
Twitch - I stream random things now and then, but nowhere near frequently enough to want to call myself a streamer.
Youtube - I think around half of my video uploads are unlisted, but if you want to see what's there anyway, there you go!
Fightcade - I mainly play Street Fighter Alpha 2, though I'll also sometimes play Alpha 1 or TGM2.
I also have a Cohost account, though at the moment, I don't use it.
