Read a couple of articles this evening that pointed out some design issues with Masterdon/Activity Pub, mostly around bandwidth/caching (i.e., when somebody popular posts, their server will get lots of hits as the server of every follower picks up the message), but also the need to be hosted on an instance with a not-crazy admin (which is basically self hosting, except then you don't get the "community" stuff).
I dunno. I get, intellectually, that there are probably people out there interested enough in the stuff that I say to want to read, and even maybe comment on, these posts, but I have a hard time believing it On the other hand, if I don't provide some kind of feedback, I'll never find out.
I was looking into webmention a few months ago, I could pick that up again. Or I could, y'know, just add comments.
