I wonder if part of it (besides keeping positions open just to see what is out there) is that companies can use job openings as analytic data. you find information that re-affirms how much you should be paying employees, expectations of employee turn over, and more interestingly what the competition is doing. I mean, imagine I am google, I fain interest in a job posting to get some facebook employees to apply. I even give them an interview. between the resume, cover letter, and interview I might be able to get lots of information on what projects facebook is working on and then just turn down the candidate after 3 interviews and say: google is quirky, if one person dont like you, you dont get in no matter how good you think it went.
