> I think if the names are flipped - if your company was named mint.com, theirs wesabe.com, then quite possibly you win.
Whoa there, you're jumping to extreme, unsupported conclusions. No one disagrees that Mint's branding is great. But to count that as the main reason why they won? Even top 3-5 reasons? That flies in the face of the wisdom given by every successful startup veteran: it's all about execution. If Mint.com hadn't provided the instant gratification that got people talking, if they hadn't won TC50, if they hadn't spent heaps of money on marketing, they would have been dead in the water.
Don't get me wrong: branding is important. But if your product+marketing is inferior, you'll probably lose, and if it's superior, you'll overcome all but the most disastrous names. (Nobody knew what a googol was, most people still don't, and look who's running the show.) You're focusing on the name to such an extent that you're ignoring most of the factors that lead a business to success or death... it's like MBA guys who've never built a product in their lives, yet say things like, "Oh I'll just outsource it, it's not important." Yeah right.
