BuzzStream co-founder and CEO Paul May said this week that his Austin, Texas-based company unveiled a free open beta of a new Discovery search engine for finding complete info about influencers.

BuzzStream’s main tool, called Outreach, helps marketers find, organize and maintain relationship-based marketing tasks, like organic link building, generating publicity from leading experts on a given subject and so on.

With the new Discovery search engine, you enter a search term, and the engine returns a listing of people who have written on this topic. The results are sorted by the most influential — that is, the ones whose posts have the most shares and who have written for the most widely recognized publications or sites. You can filter by the number of Twitter followers and other parameters.
