In my opinion rants are useless. 1. they are very long normally. 2. not organized in a manner one can follow the meaning 3. contain some facts which can be distorted and out of context 4. contain opinion of the person giving it without knowing his or her knowledge of the subject and were it was obtained 5. tend to ramble on repeating themselves many times 6. no foot notes to show were facts were obtained. So why even bother to read one. Charles Nighbor Architect and Engineer
