and an fyi from my perspective; You can ALWAYS have a
   full-fledged discussion on my wall. Discussion is always
   appropriate and when you're "in the zone" of a conversation, new
   ideas spring forth that might not spring forth if the
   conversation is halted and returned to later on. Sometimes you
   can't repeat the initial conditions that started the
   conversation in the first place. So, for me, don't worry about
   rudeness. To me, it's a honor to be graced by intelligence on my
   wall or anywhere that I'm around smile emoticon
