I'll be impressed with Pinwheel if it makes money. I'm impressed when any startup has actual revenues (revenues such that a gigantic user base increase is a good thing because you have money to pay for more EC2 instances) and you don't have to be a "celebrity entrepreneur" to make money. Good ideas with great execution with a solid path to revenue make money, and you can be a guy in a coffee shop (or someone spending 2 hours a night after work) to do this. I'd say that your potential customers don't care if you're a celebrity or not if the thing you're building seems valuable to them.
