You really don't read much of this list <0.9 wink>.

Yes & no.  Zope lists have a clear focus, but c.l.py is all over the map,
from Alex Martelli discussing the right kind of water to use when preparing
pasta, to debates about Microsoft's place in the world.  You can't really
can't imagine what a sprawling zoo c.l.py is until you've stared at 20,000
randomly selected msgs for months.

But what they all have in common is ALMOST NO ADVERTISING.  I believe that
makes them much easier than personal email, barring the one-word subscribe
etc thingies attached to mountains of employer-generated disclaimers.

Yup.  But since there *is* a non-zero FP rate, and always will be, dropping
email is probably not a politically acceptable option (even if the FP rate
is lower than the chance of a mail-transport screwup losing the mail).

I believe that's not lost on Barry either <wink>.
