Oh I learned plenty from USENET over the many years I read it
daily, and I still do read it from time to time when I can.
Alas, even with killfiles it's often just too much noise and
not enough signal to make it worthwhile anymore. My ideal is
that a site like this could and would be different, something
like the difference between open and moderated newsgroups, but I
guess that is not to be. I hear you, I appreciate the advice, and I'll start ignoring them.
