Nice to see more company friendly/recruiter unfriendly job boards out there. My own effort http://jobstractor.com scrapes jobs from twitter, removing the jobs boards and recruiters is getting some traction.
Have you plans to improve the search on the site? I think that would be the biggest benefit to me. And are all the jobs on there still active? Ie some are quite old but do employers remove them once they're filled?
All the best with UseTheSource, Robin
