One of the first fediverse accounts I made was a pixelfed.social and it has served me perfectly for almost a year now.

I've been using https://metapixl.com for a while, (well, not really using because I have nearly zero use for it, but anyway), I think it's a really good one since it has the most generous resources of the ones I looked at over on the Pixelfed instance finder.

From what I've seen so far the whole place looks like a ghost town though, or maybe it's just me not having experience with interacting on Instagram-like software so it seems like the activity is barely existent, nearly no likes nor comments anywhere I look on average, however there are quite a bit of posts!

I've been on Pxlmo and I love it there so far, except for some reason I've never been able to get video posts to work. That's probably just user error though.

EDIT: I forgot to mention, I've also been using it as an image host for posting pictures here! I kinda figured that, since Pixelfed is literally designed for picture sharing, it might be better at handling all those files? Hopefully?
