On top of the other issues mentioned, I would add that, the whole point of your site is for people to go to other sites. Meaning, when I'm done using your site, I'm not looking at your site anymore, and therefore I'm not clicking on your ads.
Compare that to a blog of new content, even if it has far less traffic than you have. When I'm done looking at that content, I might have no idea where I want to go next. Then, an ad catches my eye...
So, a site that encourages people to go elsewhere will inherently have more challenges getting a high CTR, in my opinion.
