How do we know this is better than Quantcast? Does anyone know where the data comes from? Also, it seems to be missing some of the features.
For instance, it looks like the demographic data is absolute, instead of the percentages being relative to the totals for their data set, so it's hard to tell if my site is popular among people who earn over $100K, because they only make up about 1% of the audience.
