the truism seems always to be true; and why I prefer online
  communication in general; many ppl seem to spend more time
  tolerating the other speaker and waiting for their chance to
  speak, only listening for keywords to latch onto... OR, more
  commonly, paying no attention at all and just continuing their
  dialogue. Then again.. it's likely I do the same when given a
  chance to speak.. so I usually sit quiet and do the "good
  listener" routine, ask appropriate questions, play mentor.*
  Seems to work.
