Personal datapoint: I loaded up Threads when it was announced, and then said "meh" because there wasn't enough content at the time. This post actually reminded me to take a look at it again and now I see much more content, so I'll take a second look at it to see what's there.
Also - Still waiting on my Bluesky invite.
You should just try Mastodon. Recently I found I can get >50 boosts+favorites frequently with my mirrorless snaps.
