Just wondering... anyone have a theory as to what are the demographics of MSN searchers as compared with Google & Yahoo searchers?
The purpose being, in order to guess at which ad campaign topics for which kind of sites would do well on MSN AdCenter ?
Good for high-tech subjects? Low-tech subjects?
More young people topics than retirees?
More entertainment topics than business topics?
ideas...?

I think that MSN searchers fit in one global category brain-washed. If you have microfost-a-like product you could make a good money advertising on their network.
