Not listing the compensation means that many potential applicants never even saw the role. It's 2015 yet many of these job sites will not display a role if one (as the potential applicant) has specified a salary range but the listing didn't include it. Another consideration: if there's ten roles I'm considering and yours is the only one which doesn't list compensation, I'm not going to waste my time applying for the role. You're competing in a marketplace for limited resources, failing to say how much you're willing to pay doesn't tell me anything about your company culture, it tells me you're unwilling to say how much you'd pay in compensation.
