Consumer magazine Which? reports this month on Webwise, an internet behaviour monitoring service.  Webwise follows your online activity to build up a picture of your browsing habits.  Phorm, the company behind Webwise, say that the service does not breach privacy as the profile built up is anonymous - they do not have your name or personal details.  Advertisers buy the information from Webwise/Phorm to send you targetted adverts & promotions. 

Is your ISP considering using this service? BT, Talk Talk & Virgin Media are all evaluating Webwise, and BT have already conducted customer trails.

Would you opt in or opt out of this service?
