From Microsoft’s Audience Intelligence adCenter Labs comes this tool for Demographics Prediction which claims it "predicts a user’s age, gender, and other demographic information, based on their online behavior, such as what queries they search online and what web sites they visit"– based on MSN search which is… well…. not quite *the* web demographic. But the good news is, for people who search sith MSN, the CogDogBlog audience are males less 18.
Of course it does not reveal if these represent 10,000 data points or 10.
They explain it:
This tool uses a user’s search queries and Web page views to make demographic predictions. The General Distribution results show the age breakdown of MSN Search users, based on a one-month MSN Search log and regardless of search query used. Predicted Distribution depicts the predicted breakdown by age of MSN Search users for a single search query, based on the adLabs predictive model.
