A system and method for facilitating social interactions between different individuals. Information available about each of the individuals engaged in a social interaction is used to provide a “social accelerator” for an interaction between the individuals. Social interactions are improved or accelerated by aggregating available information about individuals participating in an information system.

A social accelerator is selected from available interest information common to the participating user and the target user, and the social accelerator is provided to one of the individuals.
