"The overture results for domainname.ext is supposedly suppose to show you how "popular" a name is. "
Sorry Omni but totally wrong.
I would say 0,000000000001 % of people put in the url into a SE's searchbox if at all. People use SEs for SEARCHTERMS,not for URL's.So to check how many searches on overture where done for an URL is just nonsense,sorry.
As for the hyphens: Even if it is a hypenated .net - as long as it is a generic searchterm domain that has high searches on overture (meaning searches on the TERM,not the DOMAIN) it still is a GREAT searchengine name that if optimized and developed is A LOT more worth than reggin fee.
