IdeaScale enables companies to build living / breathing Digg style communities. IdeaScale is based on the simple model of crowdsourcing. It begins with an idea posted to your IdeaScale community by a user. Each idea can be expanded through comments by the community. The ultimate measure of an idea is determined by a voting system. Any idea can be voted to the top or buried back down to the bottom. It combines the "wisdom of the crowds" concept with Web 2.0 models like Digg.
