@riemannium @axbom Image sharing on Fedi is the focus of PixelFed.
People often say that the FB-like on Fedi is Friendica. I'm on Friendica and I don't entirely agree, but it's certainly more FB-like than Mastodon, Pleroma or MissKey are. It's visually oriented around conversations and the original posts that start them rather than being a stream of equally treated comments.
My brain is calmer on Friendica than on Mastodon, Pleroma or MissKey. It doesn't encourage the dopamine flow and the FOMO the same way.
