I’d like to point to my request for Fediverse-wide Interoperability especially for Mastodon.
Fediverse-wide Interoperability

TL;DR I want Mastodon hashtags treated like communities. Given the following _homomorphism_ (morphism, analogy) between microblogs like Mastod…

Should clarify that I don't just want to follow users, I also want to be able to utilize my profile as a microblog and be able to make 500 character or whatever mini posts straight to a tab under my profile. Like in addition to posts and comments I want microblog and replies to be tabs on my profile and included in my overview tab.
This is me still hyped to switch to piefed when it's got a microblogging function.
