Finally, it is worth mentioning that many studies of on-line
communication have shown that electronic links have a de-inhibiting
effect on people.  Deprived of the body-language cues through which
emotional state is expressed, people tend to forget everything about
other parties except what is presented over that ASCII link.  This has
both good and bad effects.  The good one is that it encourages honesty
and tends to break down hierarchical authority relationships; the bad is
that it may encourage depersonalization and gratuitous rudeness.
Perhaps in response to this, experienced netters often display a sort of
conscious formal politesse in their writing that has passed out of
fashion in other spoken and written media (for example, the phrase "Well
said, sir!" is not uncommon).
