If you have art that fits into specific stuff (Dragons, Elves, TTRPG, furry, etc) always tag for that as well. Elves specifically have the ElfEnjoyers Feed for example. I am still looking around for OC tags that fit my stuff and often just do a lot of guess work.

for asks specifically I'd use OcAsk, AskMeme, OcMeme and AMA. And if you are a bit aggressive with RTing your own posts you can circumvent the timezone issues pretty good.

Ahh yeah, I've definitely used some of those but it never hurts to keep using them and adding the ones I haven't used yet, tysm Micah!
