I understand your comment regardings SEO, and I agree... however I was not talking about SEO but monetization. I also get your mean about traffic, but that's not really my concern either.
I know that there are a lot of sites who would pay a monthly fee to have a link to their site from here, integrated into the content somehow. A blog post, a signature link, a footer link, etc. I'm deeming the value from the pagerank alone, not taking into consideration any other factors. i.e he could sell 10 footer links on the main page for at least $35/month a pop. That's at least $350/month right there from just one page.
These sponsors wouldn't care about the traffic generated, only that search engines see a link coming from WP... thats what they are paying for.
It's okay to link to other things in the "health/medical neighborhood" and still be relevant. For example, a link to fitness type site would be okay, because excercising is important for mental health. Now linking to a casino, or a site about engine repair would be considered suspect.
