Kbin was forked to Mbin which is community run. Kbin seems to have stopped development while Mbin continues. Most kbin sites have moved over to Mbin I think.
Not sure what's happened woth kbin.social though. Maybe its moving to Mbin? Still seems yo be running kbin currently judging by the landing page?
Mbin should be merged back into lemmy. It's a successful experiment and the microblogging portion is a killer app... But it'll never get the volume of subscribers to matter
You can't view microblogs unless they include a hashtag that corresponds to a Lemmy community. They can comment on any Lemmy post however. If you're not paying attention to the instance of each user you may not notice.
I don't know, it's just the instance I chose in a moment of need, from ignorance. From what little I know it appeared that MBin was a good place to stick. I started on Kbin, but it stopped working, so I moved on to MBin. Trying to find stability in this new world. LoL.
