In total Overture's Search Suggestion tool shows 543,137 for all searches. It is extremely impressive that the least searched term they show is
#100 and has 1533 searches a month!
I own a domain or two that I value (and others have too) at $15,000 + and I would trade them for charts.com any day.
Cheers!
