In December, Buffer, a startup that's created an app for social sharing, made quite a buzz by announcing that they were moving to open salaries. That is, they published the salaries of every employee (currently 15 people and growing) as well as the formula they've devised for determining employee pay. Turns out that Buffer's policy of "radical transparency" has paid off, at least so far, with a significant increase in the number and quality of job applicants.
