I spotted this article on Guerrilla Innovation which points at the development of another ad-blocking peice of technology. It made me think. If it's possible to susbscribe to a service which takes away ads and replaces them with art, in theory, it should be possible to take away the adverts and replace them with altenative messages? Maybe someone with a worthy cause? Should we start a similar network of small NGO's who need the advertising space? Just a thought.
