ads and ethics

I have an uneasy feeling about ads on this blog....Of course, I'd love to generate some income from it. However, I also don't want to be influenced to put on content that will attract more ads, or to avoid content to prevent certain types of ads from being posted. For example, I'm not really that interested in having ads that push specific medical therapies...it creates a conflict of interest, making it less desirable for me to criticize certain things. I don't mind directly consulting for corporations and disclosing that to my patients so they can evaluate any conflicts of interest, but it's harder to control against the influence of corporate ads, as some of the editors of medical journals have found out the hard way.
