Just watched this Martin Fowler presentation. It gets interesting around 10 minutes, so skip there is you're impatient.

In a nutshell, while App Sumo is just selling videos full of potentially dubious information, they have a central tenant to their message, that is very parellel to Jez's idea. Just get your business going. It doesn't matter if it's a bit ghetto at first. Don't waste time and money on bad ideas. Find out they are bad quickly.
