{ Got this from Darren. }
You can use MSN’s adCenter technology to predict a customer’s age, gender, and other demographic information according to his or her online behavior—that is, from search queries and webpage views.
Here’s on I got for this blog:

That’s 51% male and 49% female with average age range of about 25 – 34 years old. Interesting predictions, eh. Hi to all yah ladies out there! ;)
I did another one for PTB:

PTB, on the other hand, is heavy with male readers (62% vs. 32% female) but wiht a much lower age range of 18 to 24. That’s strange. *hehehe*
Note: The statistics are based on undisclosed size of sample data and are for proof of concept only. Actual results may vary.


Bah, dead even split! And minors too! :D
