Community Memory was the world's first public computerized bulletin board system. Community Memory ran off an XDS-940 timesharing computer located in Resource One in San Francisco. The first terminal was an ASR-33 Teletype at the top of the stairs leading to Leopold's Records in Berkeley. You could leave messages and attach keywords to them. Other people could then find messages by those keywords.
