I agree with everyone else here -- sales and data come first.
I think everyone should consider how hard it must be to continue to improve accuracy. I'm SURE Ioi is beating his head brutally against a wall at this point. It can't be easy to keep adding new sources, save the larger chains coming to him and offering their sales information openly -- which isn't going to happen, because they can take that data and SELL it to the NPD.
In short, I assume that coming up with reliable, consistent, large scale data samples for free is tough. Really tough. I bet it's hard going, Ioi, but keep trying! We all appreciate it!
