If your product is killer I don't think it matters what your domain name is. People are going to get the word out.
Look at "blekko" for crying out loud.

If we succeed, the name will be considered great. If we fail, people will blame the name. Does the name really affect anything? I bet good results are more important.
I'm of the opinion that if you don't have creative enough people on your team to come up with a good name you probably have bigger problems than the lack of a creative name.
Note: I'm a fan, and hope you guys kick ass -- I'm just being honest with my opinion.
