I was going to put a comment against a question that had a very high velocity of views - it was very dramatic with answers quickly given, upvotes attracted, close votes attracted and closed - all in the space of 4 minutes.
I suppose that's par for the course in the C#/Java world.
This question looked like a battlefield for high rep users, and to me it nicely represented the constant ideological difference between the SO close-happy and answer-ready factions, even among the oldies. There is even a third group present, who will sit on the fence and put the gist of what-would-be answers as comments against the question instead.
Anyway, long story short - why shouldn't we be able to see rep by hovering over the names in the close list? You can see rep against the user who posted the question and answer, and you can hover over the user in comments. Just a bit inconsistent IMHO.
