Some embodiments are directed to a computer node that communicates a report message containing information to a social media server to cause publishing of the information to other computer nodes tracking publishing on the social media server by the computer node. The computer node receives a response message from one of the other computer nodes through the social media server, and operates based on the response message. Related embodiments are directed to another computer node that communicates with a social media server to track information published by report messages from other computer nodes, generates a response message based on the information published by one of the other computer nodes, and communicates the response message to the social media server to cause publishing of content of the response message to the other computer nodes.
