I still get the blurb about increase your earning up to 100%... "To maximise your revenue, opt in to displaying text and image/rich media ads".
To me the question becomes: "What do my site visitors, now mostly returning, or from links on others sites think?"
I suspect they don't come to see garish ads, while unobtrusive text ads are OK.
Always remember, you have absolutely no control over what other people see on your sites. You might think you have some idea, but I believe reality is somewhat different.
