Gatekeeping theories have been a popular heuristic for describing information control for years, but none have attained a full theoretical status in the context of networks. Network Gatekeeping Theory defines basic concepts like gatekeepers, gatekeeping and gatekeeping mechanisms and gated. It helps understanding relationships among gatekeepers and between gatekeepers and gated, the entity subjected to a gatekeeping process. Network Gatekeeping Salience proposes identifying gated and their salience to gatekeepers by four attributes (1) their political power in relation to the gatekeeper; (2) their information production ability; (3) their relationship with the gatekeeper; and (4) their alternatives in the context of gatekeeping.
In a web 2.0 world the relationship of gatekeepers-gated is intriguing. The users ability to produce information and the dynamic relationship between users and gatekeepers makes NGT (Network Gatekeeping Theory) a great framework to analyze these chages.
