I've been using mastodon for a few months even though not very actively, so when reddit shenanigans took a turn for the worse, I looked for an alternative and found out about kbin.
For me it was pretty straight forward. Following feeds from other instances is simple enough to do but the exact user experience varies depending on which service you're using.
Right now from kbin, I'm following my own mastodon account and a few communities from mastodon, a couple from lemmy and several from beehaw.
Personally, I'm hopeful. I think as more people figure things out and the culture of the system starts to spread more mainstream, it (the fediverse as a whole) will make a good platform for all sorts of social media needs from twitter-like microblogging to forum discussions.
