Unsure that this answers the "Top Sites" question ... more research required on my part, IMHO.

What I like to do, though, from time-to-time is go to Google "
Advanced Search":
Link:
http://www.google.com/advanced_search?hl=en
Domain: ONLY return results from the site or domain: >> enter >> .INFO (and hit "Google Search"). :talk:
Of course one can replace .INFO with ".US", ".BIZ", etc.
It's kinda cool!
