AngelList

Achoo is a professional social network built around achievements. Each achievement is a social object that can be tagged with team members, companies, skills and discussions. These achoos, as we call them, are much more informative than fancy job titles that you see on LinkedIn or a static portfolio that becomes out of date the minute it's published (Zerply etc.). It's great for freelancers, creatives, consultants; useful for almost any professional.
