just being pedantic here, not confrontational, but loops.video is implementing federation but hasn’t finished yet. i was a tad disappointed but have hopes for the future that they get it done and it doesn’t flounder
Well the very simple version is that it's an Instagram alternative (I assume 5 year olds know what Instagram is). Similar in almost every way, minus the ads.
Theoretically you can use it to share photos to Lemmy, but I have no idea how. There was discussion of Pixelfed groups at one point, not sure if they ever came to fruition.
I don't really understand it either. I think it's dumb. And I think PixelFed is dumb. And Mastodon. And Loops. But I'm glad they exist. Everyone is better off if people start switching. Everyone except Meta.
