Thanks a lot namenut...rep added for such a thorough response. I'm of the opinion that USA while seeming a generic term, makes a name brandable. Blog.com is obviously generic but BlogUSA.com would be considered brandable, and while that can ultimately help it sell for more to an enthusiastic buyer, it being brandable makes it harder to sell. Still, I would say it's a great USA name...I have another good one, GamblingUSA.com, and even it doesn't really have the effect that BlogUSA.com has, though I guess given that recent bill passing, GamblingUSA.com could be made into a political site also, heheh.
By the way, yes it's for sale...I added it into the thread that's linked-to in my signature. If you want to make an offer on it, let me know. I still have to think about how much I would want for it.
