>Don't say "thank you" for a useful post because it takes up too much time and space? How utterly ridiculous.

The comp.* hierarchy and probably most of the rest of Usenet in 1992 had the ethic that you should not waste a whole message on just a thank-you (thank-yous sent by email were fine, and in 1992, almost every Usenet From field contained a valid email address) or on any other purely social nicety unless perhaps the social nicety's purpose was to conclude or cap off a long series of back-and-forth messages.

Usenet was probably where a good 40 to 50% of thoughtful public discussion happened on the 1992 internet (the other places where much public discussion happened being mailing lists and IRC).
