Awesome find from Ask Gothamist: A 1940s phone etiquette manual, How To Make Friends By Telephone. It reminds Gothamist of the old home ec books, lying in dusty corners of classrooms, that teach you how to file your nails, make a pot roast, deal with nosy Mrs. Kravitz, and make cocktail weiners. But it's worth a read, if only to be reminded good phone etiquette is timeless.
Another way of making friends by the phone, aside from 976 numbers: dodgeball. Earlier thoughts on cellphone etiquette from Ask Gothamist. And Gothamist on computer etiquette at people's houses.
