That's funny. The first time I heard of bingo card creators I thought it was a great idea. That and other niche hobbies like knitting, aviation, models, etc have huge untapped potential. and they're probably much simpler* to succeed in than yet another social widget. They also appeal to my "God-those-narcicistic-valley-kids" personality. * Simple, but not easy.
