8. The medium of claim 1 wherein the messaging robot is further configured to: present questions to the second messaging identity, at least one of the questions including selectable responses associated with the question; receive, from second messaging identity, responses to the questions; access, from computer-accessible memory, stored responses to the questions, at least one of the stored response having been received from another messaging identity and being associated with the other instant messaging identity who provided the response; compare responses received from the second instant messaging identity to the accessed stored responses; identify, based at least in part on results of the comparison, a group of less than all messaging identities who are currently connected to the chat room system, the group including the first messaging identity; and use the third messaging identity to introduce the identified group of messaging identities who are currently connected to the chat room system to the second messaging identity and to introduce the second messaging identity to the identified group of messaging identities who are connected to the chat room system.
