A method and service method facilitate collaboration with, communication of, and access to information, particularly in an education environment. One or more sets of respondents are selected to respond to one or more queries from a querent by using a strength value between the querent and one or more of the respondents in the set. One or more responses to the query are received from one or more of the respondents. The strength values of the respective respondent are updated by an assessment of the response. Updated connections for future queries iteratively evolved, based at least in part on the updated strength values. The updated connections are stored in a data structure such that a computer can access the data structure to obtain useful responses to the future queries. In some instances, the steps may be performed as a service and a fee may be charged.
