, and Szpakowski user interface and information husbandry. Community Memory in its first phase (1973–1975) was an experiment to see how people would react to using a computer to exchange information. At that time few people had any direct contact with computers. CM was conceived as a tool to help strengthen the Berkeley community. Their brochure states that "strong, free, non-hierarchical channels of communication--whether by computer and modem, pen and ink, telephone, or face-to-face--are the front line of reclaiming and revitalizing our communities."

Brief instructions were mounted above the modified keyboard showing how to send a message to the mainframe, how to attach keywords to it to make it searchable and how to search those keywords to find messages from others.[ To use a Community Memory terminal, the user would type the command ADD, followed by the text of the item, and then by any keywords under which he/she desired the item to be indexed. To search for an item, the user would type the command FIND followed by a logical structure of keywords connected with ANDs, ORs and NOTs.][Colstad, Ken and Efrem Lipkin]
“Community Memory: A Public Information Network”
ACM SIGCAS Computers and Society Volume 6 Issue 4, Winter 1975, p. 7 By the side sat a CM assistant, attracting people's attention and encouraging them to add and find messages. In its approach, Community Memory adopted a creative method to funding the project. They provided users with coin-operated terminals which could be read without charge; however, in order to post an opinion, users were required to pay twenty-five cents or one dollar to start a new forum.
The record store and its bulletin board brought together drummers seeking fusion guitarists, bagel aficionados looking for sources, and the first poets of the medium, notably one who went by the ''nom de plume'' of ''Dr. Benway'' — the first net personality.[ Periodically directories of recently added items or of musician-related messages would be printed out and left there. In other terminal locations, users sought out complete strangers to assemble car pools, organize study groups, find chess partners, or even pass tips on good restaurants.][ According to Colstad and Lipkin, the rate of use of the system was fairly high and constant in relation to the environment of the terminals. About fifty searches and ten additions occurred each day at each location. Given the length of individual sessions with the system this was at least one-third the maximum capacity of a terminal.][
Anonymity was possible with Community Memory because users were not required to share their names or register to use the system. All of the information on the system is community generated, which has two implications. Firstly, there was no central authority of any kind that establishes what information is available in the system. The second implication is that information is not imported from other sites.][
