I'll probably get criticized for this too, but way too often instead of getting help on Stack Overflow, I get edited unnecessarily such as changing some bullet points to remove the bullets or changing SQLServer to SQL Server or Domain Controller to Domain controller.
It's a waste of time for me to go through and make sure the editor didn't miss something important which just happened when a large bunch of edits were made on a very detailed question and the editor accidentally deleted a very important piece of the issue.
Then the question got closed as off topic even though there are dozens to hundreds of questions that are very similar that are not closed. If all that energy went to actually helping instead of frustrating users it would be a lot friendlier place.
Also it would be nice for reputation on one of the Stack Exchange sites and to carry over to the other sites instead of having to build a whole new reputation. It is not encouraging to get treated like a noob every time you go to a new site.
I know Stack Exchange sites are very successful, so I'm sure these things have been thought through, but for this user it makes it the second or third or forth priority site I go to in order to ask a question.
