Yet, last few days I've been noticing a lot of such edits and not sure what to do. Some users even go on retagging rampage, updating every question they can lay their hands on (you can see them repeatedly in the list of pending edits).
I don't mind those guys getting their lousy 1000 reputation this way (well, only a little), but somehow I feel that the system was intended for slightly more substantial changes.
What would you do in this case? Approve or reject?
