A talker is a server that speaks the telnet protocol (usually on an unprivileged port). Users log in, and then use commands like "say", "emote" and "tell" to communicate with other users. There are usually a collection of public "rooms" (similar to IRC "channels"), with residents being allocated private rooms in which to sit and be idle, or perhaps to have net.sex.
