Werner Vogel has developed an interesting way to evaluate conferences. I posted some thoughts in the comments section. I think this could be turned into a microbusiness. This is in the same vein as the evalution model I worked up at Gomez to help people find the online brokers and banks that best fit their needs (it was also a business that generated $500 k a quarter in profit). Even if it only generates a small fraction that level of success, it would be a nice business for a couple people. [John Robb's Weblog]
