@pratik I would say that some people use different spaces for those designs/controls/vibes. Many of us don't. I don't have distinct communities on different services. I don't have any distinct privacy controls on those services. I don't have distinct identities on those services. I understand some people do, but if you do, it's inherently difficult to maintain that unless it's incredibly porous, through a single omnibus feed.
That said, I think it's bad that modest additional controls to crossposting don't exist-- I think it would be quite worth while and not terribly difficult to do category-based posting for services, for example, or just to let people turn on more features by default in the new post window (which I'd want for other things as well). I think resistance to that is misplaced.
Crossposting is probably the part of Micro.blog that is the most complicated and least resilient. Actual blogging issues have been incredibly rare.
