Clarity from changing "Objective C" to "Objective-C", whatever. The rest of the changes didn't add clarity, they were totally stylistic.

People are not computers, and we're touchy about stuff we write. If you want to add a tag to my question to make it more searchable, fine. If you want to let me know I have a typo, or used the wrong word or something, whatever. Just editing someone's question, especially for subjective writing style, comes across as rude.

If it's not supposed to, or if the rest of that community doesn't mind, I'm happy for them. But it's not for me, and it's not for a lot of other people either. So, I agree with the OP.

FWIW, I agree with you here. The other style changes were pointless (the "If I'm.." to "For example, if I'm.." nonsense). You can always roll back a change to your own question though. In the editor's defence, a lot of low-rep users post really unreadable questions. Maybe he saw you had less than a few hundred points and got a bit trigger happy.

I would roll it back, if I cared at all about the site. This all happened about a year ago, I'm only pointing it out now because it's relevant to this thread.

It's a really poorly-thought-out feature: new users who can't write coherently get taught that they don't have to, because someone will come along and fix it for them; new users who can write are more likely to be annoyed by other people playing copyeditor on their posts. Guess which group sticks around?
