1. A method comprising: processing search queries based at least in part on one or more search query parameters to identify candidate search queries for an exchange of search related communications, wherein the identified candidate search queries originate from different computing system sources or from different users, and wherein the identified candidate search queries are considered argumentative, debatable, or subjective based, at least in part, on the one or more search query parameters comprising click-entropy greater than a threshold value as a measure of discussion-orientation of the identified candidate search queries; and determining that a query from a user exhibits one or more measurable or scorable parameters overlapping one or more of the identified candidate search queries for existing on-going search related communications based, at least in part, on the frequency of the query from the user and the identified candidate search queries having resulted in users navigating to identical network locations and in response inviting the user to participate in the exchange of the search related communications; and limiting a length or a duration of the exchange of the search related communications.
