The other option is twitter, which strangely has a awkward behavior since it has both the top level segment and the entry level segment. BUT it depends on the country of interest.

Online recruitment in present times had developed in to a fundamental qualification for any HR professional. So get on twitter, facebook and importantly linkedin if you are into recruitment.
