Description
"StudyCurve melds social networking with education to help middle school to graduate school students find experts to answer questions and to form virtual study groups, Allina said.
StudyCurve users create online profiles with a list of their classes, interests and subject areas. They can post photos, form groups on various topics, and designate "study buddies."
Users can ask questions that StudyCurve sends out only to other users who tag themselves as having expertise on that topic. They can provide answers and rate other people's answers. People whose answers get a certain amount of high ratings become listed as experts.
Unlike "expertise location systems" that some companies use to help employees answer questions or find experts in-house, StudyCurve offers the potential to pick the brains of millions of users." (http://www.forbes.com/feeds/ap/2007/08/14/ap4017760.html?)
