I was quite dismayed when I visited this thread yesterday, but I left without a post in the hope the point you made would be grasped. Perhaps the digital field is so new that very few understand it. I cannot claim to be one who does, not at all, but the statements in the "article" of reference are -being gentle and positive- misguided and misguiding as proven here. The Internet is a wonderful world but not foreign to charlatans, those we were running away from when we founded this community. Thanks BJ for being here.
