paper-net (n.)

Hackish way of referring to the postal service, analogizing it to a very slow, low-reliability network. Usenet sig blocks sometimes include a

Paper-Net:

header just before the sender's postal address; common variants of this are

Papernet

and

P-Net

. Note that the standard netiquette guidelines discourage this practice as a waste of bandwidth, since netters are quite unlikely to casually use postal addresses. Compare voice-net, snail-mail.
