Micro.blog's implementation of ActivityPub is really compelling for a few reasons:
- Defaults to your own domain
- No boosts
- No likes/favs
- Strong micropub and RSS features
- Custom design for your page if you want it
- IndieWeb interop via web mentions and websub
- Automatic mirror of the entire site to GitHub
Not planning on switching in the short term but it's a really tempting long term option.
