Free printable cardboard lens hoods are a simple, but excellent example of lateral-use of the Internet. Most people would be trying to conjure up ways of flogging these, but Paul Mutton has the model exactly right: build it and they will come, load-up with Google Ads and stand-back. I have no idea how much Paul earns from this site, and if the (fiscal) ends justify the means, but I just find it poetic in its distillation of Web 2.0 (or something).Paul, if you are listening, get in touch and give me some background for an update please!
