In my last post I commented on Chris Fralic's observation that it is surprising that enabling users to control their own ads doesn't get much attention. Letting you control your own ads is only half of what makes XooXooX CleanWare different. But other half of what makes XooXooX CleanWare different is that your shopping preference data is stored and ad selections made client side. When you choose to use CleanWare, you have more control over your privacy. Today I would like to discuss how CleanWare is different from competing ad selection technologies and why it took so long for CleanWare solutions to become available.
