You can never discount anything, look at shoes.tv reported sale at $18000 on GD today, 2 years ago nobody would register tv domains ( although the pricing structure didn't help) . Now info and me have good reported sales.
I registered an info which is now at a £500 bid on sedo, If I had asked for opinions they probably would have come down on the side of caution. Whatever you register try not to keep adding more words than neccessary to your name, the more obscure the suffix the more to stick to the basic rules, short, generic, product or service, memorable, etc. etc.
