There are at least 2 types of people that are looking for jobs: One that is actively looking and second, passively. Most of the job search is addressed at the former. I'd pick the second type of folks - there are no specific channels for this section.

The way i'd go about it is this:

   - build a site that lets people log in via LinkedIn or upload a resume

   - the service then sends a monthly email with top 5 opportunities. 

Opportunities shouldn't just be keyword matched - it should sell those jobs - maybe they offer a better position, better perks or even a new city).

If you build this, keep me posted :)

I believe http://streetid.com/ are doing something similar for the financial world

I believe LinkedIn and Glassdoor already do this.
