Whether or not you're an active job seeker, hiring managers can now access a dossier describing your professional experience, work history, skills, passions, and interests, built from data culled from dozens of social networking sites. The information gets compiled by IT job site Dice's new Open Web service for recruiters, which scours some 50 social and professional networks -- including Facebook, Twitter, Google+, Blogger, Quora, GitHub, and Stack Overflow -- and "billions of Web pages" to generate "super" profiles of would-be job candidates.
