kluster launched its free public beta. kluster is a web-based platform that enables communities to collaborate and decide. kluster's philosophy is that development and decision-making is better served by engaging groups. kluster's founder, Ben Kaufman, is 21, and comes from his first venture, mophie, an iPod accessory company. kluster participants will work on a variety of initiatives including product development, marketing and advertising, event planning--virtually any decision-making activity better served by asking a group. Community members will contribute based on their experience and interest. Decisions within the site are made algorithmically by assessing the weight of each community member's vote based on their participation, past successes, and risk.
