You know, if you told people you were fucking around and breaking things again, it's a lot easier for your user base/eyes on ads/whatever. You make something that people use and enjoy and learn to work with, then you go improving things and make it useless for the people who actually use it.
Most admins on big sites at least tell the people who use it that you're gonna tinker with code or whatever, and people won't bother writing/composing/replying until you're done, and it's fine. Old revisions were annoying, but the kinja transition has been the worst, because it works, then doesn't, then kind of does, then doesn't again.
Tl;dr: you're doing it wrong.
