Strong words? Isn't it what most people would say? (Or at least think - I doubt they'd say or write it to you - that would be rude maybe. That's why I thought my honest first reaction might be useful.)

My second reaction was thinking about it and asking you some questions. Hmm yeah, I guess you don't need 100% coverage of people for it to be some use. (Personally I don't have a phone number, but I guess that's unusual!)
