All what they said above but this is my view on it:
1 - theres no such thing as a "too cool" design imo. The design is nice but its wrong for a free site (as mentioned above).
2 - Maybe u bought crap traffic (who knows
3 - .us domains are shit and usually people will forget it was .us and goto the .com version of it. All domains are shit except .com if u cant get .com then maybe maybe if you really want it go for the .net or .org version but only as last resort.

i hope that helps. peace
