@prologic It seems to me this distinction is pedantic and mostly at the server level. I have a mastodon account and I have no impression that I am being forced to read things I don't want to read. I follow the people I want to follow, I mute or block the people I don't ever want to see. It's almost exactly the same reading experience as I have on yarn--different people and content obviously, but very similar functionally speaking. I think there are other issues that are of more concern.
@email@example.com I think you are talking the user side while @firstname.lastname@example.org is talking protocol side, and that means you’re talking about wildly different things.
