I find Lemmy works pretty well for a decentralised network.
It is possible to see what everyone has been subscribed to when sorting by all, and so subscribe myself to it to get it in my subscription feed.
There are nice apps like Liftoff which can manage multiple accounts at the same time, and even view instances all feed without an account on them.
Mastodon on the other hand is a bit lackluster in comparison I’d say. The subscription model is pretty had to start using as I need to either find # or people to subscribe to, and even subscribing to them. And even after doing that the posts aren’t that interesting or feel empty due to no comments/likes/boost.
Maybe I subscribed to the wrong #, but I find Lemmy much more enticing than mastodon.
