Looking outside the class!

In response to a blog that I read about Contextual ads, http://sugarbank.com/2006/04/18/contextual-ads-in-context/, I would have to agree with the writer.  They bring up some very good points on how contextual ads should follow the theme of the site.  For example if the site is about exotic pleasure a good contextual ad might be one for dildos or maybe even other sex toys.  However the way contextual ads work is they categorize what is on the site and try to get an Ad of something related.  However when the contextual ads misunderstand what is on the site, the ad might be something completely different than one that you would want on your site.   I think that with all of this recent technology that we should be able to create a system that would allow the site owner to choose exactly what type of ads that can be displayed on his site.  That would just make life to easy right!  Why would people want to make things that make sense.
