I have spent an entire morning playing games on likebetter.com. The idea is a very simple one, select photos you like from those presented to you and the web application will attempt to guess your personality traits.
Some truths about myself the application recounted, “your the sort of person who rarely misplaces things”, “you enjoy sarcasm”, “your somewhat laid back today”. The last one was hilarious considering my time spent on the site :). The site is almost like a mirror of mind and personality.
It remains to be seen how the founders will turn likebetter.com into a sensible business. I can already see signs that a social-community structure is being implemented around the application. The company is a Y Combinator startup. I read about likebetter on TechCrunch.
