I charge nothing for listings at http://www.warplife.com/jobs/computer/ and they are permanent.
Among my objectives is to eliminate the corrupting influence of money from technical hiring.
In the long run I want to cover every occupation in which one can find a job by applying through the employer's website.
I won't monetize it in any way. Or perhaps I could say I will monetize it by offering my consulting services through my website, as I always have. Providing free content on my site results in sales leads.
