Abstract: The present invention provides systems and methods for initiating relevant communication (e.g., text, voice, video, etc) based on a shared experience. Each client in a system includes a presence detector which provides information about a user experience. The information can include, for example, web pages viewed by the user, content metadata associated with the web page, a location of the user, software applications in use by the user, and the like. A centralized server in the system can quantify the proximity between experiences of two users can be quantified with a correlation score. If the users exceed a predetermined threshold for the correlation score, they can be connected into, fore example, a chat room or video conference.
