I am not sure about the "digit-heads" moniker, but I guess it fits.
[Normally, I reserve words like that for CPA's who work with true digits all
day long... we work with "bits" and "bytes"... but I don't even like the
sound of "bithead"...]

I enjoy the off topic posts.  If I have time I read them (and even
occasionally reply).  If I am "hunkered down", they get deleted before even
being read.  Since I work from the house, I enjoy the "contact", the humor,
and the frequent wisdom that is imparted because of these types of posts.
Of course I enjoy the HP related topics as well (since that is why I
subscribed in the first place...)
