I think this is an important point to consider. For a long time, I kept thinking that the fediverse was going to be the answer to the problem of keeping separate accounts on every site (because most places are isolated/walled-in networks). It took me years to accept that "one account everywhere" isn't what the federation model is about.
I wish there was such a thing, but that's going to require portable identities/user accounts, and I don't know why but that seems to be progressing at a snail's pace with a bunch of stagnated RFCs everywhere (but please let me know if there is progress happening somewhere, I may be out of the loop). Once we have that, it'll make the fediverse a lot more convenient, since then you should be able to log in to other instances with the same account.
It has a particular style of writing that pops out after you read enough of them. The caveat is that it can be made to change it up enough that you can't tell. Just tends towards a certain style by default.
I added the izzydroid repo and I don't know if the repo just isn't working or what, but there is no newer version listed for me.
