> In my opinion, Genius is not as compelling of a product to work on as they seem to think.

I guess it could be helpful to define what the product exactly is. Genius is a high traffic transactional site, so they probably have the same problems that any large site has. They're also incredibly text heavy, and I probably wouldn't being going too far if I said that they are striving to eventually have every piece of written text available. Looking at these two qualities alone, I feel that there is enough going on to make their product compelling to virtually any person that has done software engineering, applied statistics, machine learning, or read a book.
