Congrats on the launch! I remember when we (I was a former groovesharker) started working on it back in November of 2010! Great to see that you stuck with the project through what I'm sure were many ups and downs :)

I'm curious to know how you see the product benefiting people. What do you see people actually using it for?

Right now it seems like a cute demonstration of a data mashup though not entirely factually correct. For example, if I search for "Coldplay" it says 85% affinity for Asian Indian and 82% Plastic Surgery and high Z-score for Hindi? How do you ensure the accuracy of this data?

I think you need to display the results of this data differently to users. If its correct, people without statistics backgrounds will get confused because not everyone can interpret what a z-score means, nor will they understand how it is useful to them.
