As someone who doesn't use Cara, Pillowfort, BlueSky, nor Mastodon (still in the process of being active on Sheezy),
Do you have any opinions on any of them, solely from your experience?

Apologies for a slightly late reply but I'll try to summarize each of my experiences with these:
Cara: I haven't done a whole lot with Cara as of yet and haven't got a lot of feedback from other users either. It feels very like Instagram in that way.

Pillowfort: I actually think besides FA and sometimes Bluesky this is where I get the most likes and shares on my work. The site is suppose to be a kinda tumblr alternative but I find myself using it more like Livejournal used to be. Ya know joining communities relevant to my interests and then submitting my "reblogging" my relevant art to them so people with shared interests notice it easier.

Bluesky: This is Twitter again but like... mid 2010s Twitter not modern. Site has a lot of the bad takes and discourse kinda stuff you would expect but a pretty active furry presence so its not hard to get eyes on your work.

Mastodon: This one is hard to even describe because it like if Discord and Twitter had a weird lovechild so your user experience will depend on which "instance" of Mastodon you join. The one I'm on is called Plush City and its run by an cop hating non binary person so its actually the chillest place I use on the internet. I've been using Mastodon since 2017 and I've gotten into I think 1 argument ever with a person and that wasn't even on Plush City that was on a previous instance of it I was on that like imploded because that's kinda the double edge sword of using Mastodon.

Oh okay sweet, I've been so curious about these new sites popping up but don't see myself having a chance to use them anytime soon. Thanks for sharing.
