A lot of folks discuss these names from a speculative standpoint: you want to buy low and sell high...
That's nice and all, but look at it from a developers' viewpoint and consumers' view too:
Developers want the names because the "good dot coms have all been taken" and because they want search relevance
Consumers -- your customers -- on the other hand, will (rightfully so) see these realms as the home of spam and doorway pages, typically run by foreigners, on the wrong side of the tracks, as it were.
But hey, good luck with all of that
