There’s Pixelfed which is a fediverse alternative to Instagram, but I don’t use it currently as I don’t share my photography online as LCP.

Other than that, there are other fediverse platforms that are basically Mastodon-like or Lemmy-like.

Things are fairly wonky right now, but I believe with time, effort and funding many if not all of the fediverse’s issues can be resolved.

Which Lemmy communities are you a part of that are currently tiny? I can lend a hand in posting/commenting there and keeping them active.
