TWO-WAY REAL TIME COMMUNICATION SYSTEM THAT ALLOWS ASYMMETRIC PARTICIPATION IN CONVERSATIONS ACROSS MULTIPLE ELECTRONIC PLATFORMS

Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for receiving a first communication request, from a web browser of a user. A request for information is sent to the web browser. A first communication as part of the first conversation is received from the user. A conversation identifier is identified and used to store the conversation of the first user. A request is received from a second, different, responder for the conversation. The conversation identifier is determined based on the request from the second responder. The request for information and first communication are retrieved from a persistent data store and sent to the second responder.
