Yeah actually, here https://twitter.com/johnnayderp . I mostly use it to talk about what I'm watching or what's irritating me. Sometimes those two things together. I have pretty much no audience and most of my interactions come from replying to other peoples' stuff. I also use it to receive horror news. I have a private list set up to display only the accounts I feel are most beneficial in that area.

A giant soapbox is a perfect description and I can understand the desire to avoid that entirely. If there wasn't a horror community there, I doubt I'd still have an account.

I don't think it'd be your best choice either. I follow a few artists, but all of them seem to focus more on Facebook or Instagram. Facebook's as much as of a dumpster fire as Twitter and I know little about Instagram. It's probably not much better. You could always test out your artwork here whenever you feel up to it. I might do so with my own stuff at some point.
