I host: GotoSocial, Bookwyrm, Matrix, and a number of self hosted git related services (Radicle/Forgeo). Some awesome emulators of more modern game consoles are over on the federated git (not GitHub) nowadays.

I also made a UI that transforms mastodon to look more like lemmy/piefed/etc…, where hashtags are the communities. Its not really ready and very bare bones.

I have a funkwhale account. I wish I used it more.

Most of the above have an rss feed so thats how I keep up with it all.
