According to Media Metrix, web behavior apparently also differs between Republicans and Democrats. Registered Republicans are more likely to visit business and financial news sites such as schwab.com or etrade.com as well as on-line sports websites such as ESPN.com. Democrats are more likely to visit retail sites and sites that provide specific advice on how to perform certain tasks like gardening or parenting.
Sounds like you could replace "Republicans" and "Democrats" with "men" and "women," respectively.
