As rejection comes with no explanation (understandably, given the number of YC applicants), we'd (unignorant & zaveri) like to ask the critical eyes of HN readers for some feedback. A short description of our idea follows:
BijectKarma is a place where developers, designers, and hackers can request and fulfill services for karma (our currency). By completing requests, users can build portfolios and form networks while developing an online reputation. Think of us as Listia.com, but for services.
