1. Staying. It does exactly all the stuff I need it to do: Gallery, Folders, Tagging, Simple Feed. No Social Media drama. (Deviantart Drama is much more avoidable imho).
2. I have a bunch of accounts everywhere, anyway. But on top of everything, I kinda hate the prospect of everyone moving to twitter. You want microwaved jpegs? You want an uncontrollable feed? Even worse algorithms? People you liked being awful on main? Zero media organization so an artist's feed is 98% reaction images and cat pics? Intrusive K-pop "Fancams" on completely unrelated posts? Go for it.
I said this on my dA, but that stuff deviantart is taking away? You won't find it on twitter. The stuff you still like about dA that makes it a good art gallery? You won't find it on twittter. That stuff you hated about tumblr? Everyone vacated to twitter. Twitter is concentrated tumblr, except there's no mutable tags, no easy multi-accounting to keep hyperfixations in their own box. Also it has the worst automatic cropping for images. And an even worse mobile layout than what Eclipse is trying to pull. Y'all make no sense.
I respect your want/need to boycott the changes you don't like, but holy cow the option everyone's taking is so much worse.
At the very least move to fa and keep the sfw toggle on, so y'all have an actual browsable gallery, lol.
3. "No, nothing changes" Me! I'm not voting up there since it doesn't apply....
(All of my 'you's are general 'you's and I'm also cranky and tired)
