Get sincere and honest feedback from people you know and give feedback to others
Create your personal feedback URL and spread it via Facebook and Twitter to your friends and colleagues so, that they can give you anonymous feedback.
Honest feedback helps you find out how your own self-image differs from what other people see in you. If you're lucky, you may just as well be confirmed that others think you are just the sort of person you strive to be.
To put it simply, sayat.me is a web application that enables you to get input for your own self-development.
