I'm not sure you understood the point I was making. Multiple platforms exist on the fediverse. Interoperability is a nice plus but it's not the core feature of the protocol.
Mastodon is strongest around microblogging because that's what it's built for. Lemmy is strongest for community discussions because that's what it's built for. There are options like mbin that do more to bridge the gap in different ways.
Success of a platform is mostly centered around doing a particular thing very well. There is nothing stopping someone from making multiple accounts across multiple platforms (or even the same platform).
I'd recommend trying to set up different accounts and see if you find one meets your criteria better.
