Once there was a street vendor in London who walked around shouting, “Hot mutton pies, for sale”. A man bought one and after taking a bite, spit it out and ran after the vendor. He yelled at her, “It was not hot and it was not mutton.” Her reply was that that was what she called them, not what they were.
User names are like that. Maybe I should call myself The Mad LMP From the North Pole, or Little Kid with an I.Q. of 240. But any name used does not necessarily indicate who or what I am. I could just as easily call myself Sylvan LMP and no one would know if I was a homeless person on the streets who just happened to have a computer connection, and a good reference library to obtain information, or an actual LMP who just had an attitude.
