I asked a question and an edit was made, then a notification was made to suggest I approve the edit. Someone else came along and approved that edit so quickly that I didn't even know the approval was there before it had been approved.
It's a bit frustrating to be asked to approve something and have someone else 'senior' trample over your question. The edit was fine, but given that I wrote the question, wouldn't it be better to give me an opportunity to check the edit (say a 5 minute time-out before anyone else can approve it)? Surely I'm in the best position to determine whether the edit is valid? I suppose there may be certain situations that require an emergency-edit, but I hope there aren't many of those.
It seems a bit incongruous with things such as not being able to accept answers within 15 minutes. I'd feel more engaged with the site if I could contribute in this situation. Having someone else do it disengages me and personally gets my hackles up.
Furthermore, I'm less likely to learn how to improve what I ask in questions, if I'm not able to review edits- the process of reviewing and approving is a learning experience. Having someone else come along and approve is rather like someone else showing you how to do something, rather than doing it yourself when you're being 'taught' something.
