Glassdoor

Glassdoor is a site that gives insider reports on salaries and the zeitgeists of more than 11,000 companies.

Glassdoor's goal is simple: To make salary and workplace-quality information as public as possible. The service is free, but in order to get information users have to provide information. If a user wants to find out how much, say, a midlevel engineer at Microsoft makes, he or she has to provide information about his or her current job and company. It's anonymous, and Glassdoor screens information that seems bogus or plain-old axe-grinding.

It's a cool idea and is packaged in a user freidnly way. Check out the site here.
