@slaw.. these are concrete reasons to me. I don't get it but I'm not built that way simply to communicate what my preferences are or what I'm doing at the moment to consider anything like that as "friendship". I never joined FaceBook either and if I'm analyzing, its to understand the phenomena.
At least you put sane reasoning to it w/o being "flummoxed."
Now that I know, I may contribute to what I think are good recordings otherwise its plain I don't belong here.
My dogma seems to be too easily offensive.
