Brian,
I wasn't arm wrestling...my apology if my comment was terse.
I agree with you on both points, but having been an exec.,
(not top and not a big co., lol!), back in the beginnings of
email, I took pride in reading and answering every email and
voice mail I got.

Then, scams were slim and infrequent; today, you are correct:
they should freakin know better, esp. if its some "subpoena"
which every knucklehead CEO should know it's gotta go to
Legal first, lol!

I suspect the Crackberry herd is sucked in, maybe by the smallish
screen, instant communication desire, appearing to support the
customer instant gratification thing, etc.
