Recruiter (and blogger of jobtipsforgeeks.com where I advise engineers on career/interview/resume) here, and that is pretty interesting that you take recruiter listings out of the job postings. Although you might think otherwise, I like that idea quite a bit from a pure biz standpoint. I'd think candidates would be more willing to go to a site where they knew recruiters weren't posting, as there is some 'danger' when going to sites where you could potentially apply to the same job (via recruiter listings) multiple times. Good luck with that!
