I agree, but the details of the implementation would be rather sticky. It would require a lot
of monitoring by Vroom and others to make sure that there isn't any abuse.
Well, there are a great many people with moderating privileges on this site :) Really though a job posting in the wrong area is off-topic enough to get moderated down, while one in a jobs section can get moderated up if the person is detailed (o'Reilly posts a job offering, gets moderated up to 30 :) )
Certainly the system isn't perfect, but it should work well enough. "Controlled chaos".
