If I ever had the urge to sell trinkets to photographers with more money than images, I would do it the Photojojo way. The formula seems to be: make a company completely about customer service, sell souvenirs of the whacky experience and make the process as fun as possible. Everybody's happy.
The only thing that would make me happier is to become a better photographer first. Now, it appears someone at Photojojo feels the same (and realizes the largest markups come from information products).
Introducing Photojojo University, where you can enroll and for the introductory price of $5 take the first course (on Phoneography). You can choose to be taught by a olde timey professor, a stack of pancakes or a basket of kittens.
Of course, I signed up immediately (with the pancakes). I never need to be prodded too hard into learning more and the first course is bound to over-deliver, so you'll sign up for future courses. Speaking of which, if you'd like to help Photojojo create some of their courses, it looks like they have job openings.
