I usually make minor wording changes multiple times after I post something. Is this in bad form?
I don't do repeated-edits to get my post more attention --- I'm just mildly obsessive about wording and rarely get it right the first time.
Too much editing can turn a post into a Community Wiki post. Here are the current criteria, taken from here:
If you get to 5+ edits, you may want to restrict yourself from making trivial edits, or at least work on the post via a different editor for a bit and save here at the end.
Note - there has to be a limit as some people wrote bots to repeatedly edit their questions to ensure they remained on the front page of StackOverflow.
No, there's a five-minute window where your edit doesn't even show as one. I end up doing lots of edits also. Be warned, if you do 6 or more outside of those windows, the post will move into Community Wiki mode.
