Like the question implies, I really want too get off of instagram. Its not the same space anymore, especially with the consistent push from Meta to use AI. Ive even made my profile private so those features don’t automatically turn on. Its gotten crazy there.
I thought Misskey/Sharkey was specifically trying to be a Pinterest alternative, while Pixelfed is trying to be an IG alternative and Mastodon is trying to be a Twitter alternative.
Misskey/Sharkey are Mastodon but with added or tweaked functionality, Misskey is directly forked from Mastodon iirc
