I think one thing that should be considered, is whether or not people can easily remember and spell the domain correctly after hearing it. A lot of referrals are still by word-of-mouth. There's a big difference between: "Hey check out Facebook" and "Hey check out Orkut". Even when meaningless; Spoondog is more easily retained than Fleaty. Having a .com similarly makes word-of-mouth referrals easier. BTW, I found an available .com that might be up your alley. Email me if you like.
