I've just thought of a massive flaw in Webwise that will render a lot of its targeted ads largely irrelevent to me. (Apologies if this has already been dicussed, but this particular penny has just dropped)

Assume that I fully embrace the concept and happily start using it, letting the system profile and pigeon-hole me to its hearts content.
Periodically, I will have a burst of activity on a particular subject, for example, I'm looking for a new car. I then start getting ads for cars etc. Great, I guess it's helping.

However, at some point my interest in this subject will stop (when I get a new car). At this point the car ads start to become an annoyance, especially if my next burst of activity is on a new TV. I'm now getting ads for cars when I want ads for TV's. The ads I'm now getting from this targetted ad system are now un-targetted.

What if the system matches me up with lots of different ad channels? They will appear to me to be random and untargetted. At this stage you have to ask, what is the point of Webwise?

Can the overworked PhormPR slave comment on how the ads are kept relevant through time and cater for changing subject focus?

Thanks.
