There was a review for a suggested edit by an anonymous user. To me it seems like the OP was editing after a logout due to the writing style, so I approved it.
While I wonder a bit that anonymous users can edit at all, I wonder even more that they can edit the question. I could understand that it's allowed by someone passing by to edit an answer, mostly because I'd sometimes want to do that on Internet forums as well. In case of Stack Overflow such an anonymous answer edit could improve the quality.
Is there any evidence that OP edited his own question or should that edit be rolled back (if it gets approved at all)?
