I like the idea of building professional reputation and applying for jobs. I have some questions (probably dumb?) about the idea.

- How is getting vouched from your colleagues/friends different from Linkedin recommend feature

- Your rank will define how fit you are fit for any job posting. Correct me if I'm wrong, your rank will depend on the number of vouches(?) that you get. So, ultimately the person who is more active on the site will have a better rank and I feel this will destroy the whole purpose of legitimate reputation building

- "Vouched does not rely on Search to find jobs or candidates, instead it uses the knowledge of the social network" - It will be good if you can take leverage of any of the social graphs that the user already has (Facebook, Twitter, Linkedin?)
