What is meta? ×  I noticed that I can edit old revisions of a
question. I don't want to use that feature just to learn what
it's good for.  What's the purpose of that?    • Can I beautify
older revisions?   • Can I mangle the edit history (like Git's
rebasing)?  PS: I'm mainly active on Android Enthusiasts and
also quite new to the site. This is a general meta question, so
I ask here.  share|improve this question In short: unless you
mean to Rollback to that revision, don't do that (Longer answer
is already posted and accepted) –  Shadow Wizard Jun 28 '12 at

an old revision, it'll be copied over the current revision and
becomes the new version of the post. It is a shortcut to
rollback+edit.  I would have pointed you to How does editing
work? but at the time of your question this particular
information was not there yet; I've added it in.  share|improve
this answer Well, it's there now. :) –  Shadow Wizard Jun 28 '12
