Sure, like they were successful because of the logo :-/
I don't know why we have to always take the most improbable one-in-a-time cases like Facebook, Amazon, and other huge corporations and compared them with regular folks (whom are the ones who would use this tool).
I saw that this link was second, checked it out and was baffled.
I'm glad this is the first comment, I almost got scared people were praising the service.
I agree with everything you said.
A crappy logo is 100 times worse than no logo.
