Abstract

In one-to-one communication only one individual communicates with another. One-to-many communication refers to a communicative act in which only one special person is entitled to be the sender and is allowed to publish information. In many-to-many communication, however, each participating person can post messages and each person can receive messages. Consequently, a sender does not know who the recipients are (high anonymity) and the recipients do not know who the sender of a message is (low identifiability). This is completely different from one-to-one or from one-to-many communication situations in which participants’ behavior can be clearly identified.
