For most webmasters, modern advertising services - like Google Adsense, Blogads, and so forth - are a wonderful thing. They remove much of the drudgery and effort from the process and often produce better results to boot. In my case, however, I don't want to see 99% of the products and companies that would appear on my websites if I used an automated system. I talk about "anti-aging science" and "healthy life extension," and thus there would be no end to the quacks, frauds, scam artists, and random junk appearing in any automated advertising system. The present services just don't give you enough control to squash that sort of thing reliably - at least not without spending an inordinate amount of time on it.
However, ads bring in money, and money can be used to grow the Methuselah Mouse Prize for anti-aging research. After some back-of-the-envelope calculations and chatting with potential advertisers, I think I can put something together that a) I can live with, and b) isn't going to insult you, the readers.
So look for the slow influx of paying ads - from advertisers I am comfortable with - at the Longevity Meme (and maybe here as well) in the months ahead. All the proceeds will go to the Methuselah Foundation to help with their goals.
