I just picked up the medigap.us domain name about three weeks ago. I am trying to decide whether to build it since my primary site is still pretty new (10 months old with <20 backlinks) or to turn around and try to sell it. I've had a couple of people say not to use it or it may not be worth much because it is a .US extension. But I know that .us sites can rank well. Also, it is one of the top keywords in my niche. I'm just wondering what the SEO experts think of it. Keep it or sell it?
