There was some discussion here a few weeks ago about "surveys" and the opportunity to earn revenue by displaying those to visitors.

I have a habit of linking to specific articles of interest to my visitors. Whenever I see one of those surveys before the article can be read, I avoid linking to that article, search for the same information where a survey isn't spashed in front of a reader and post a link to that presentation instead. One source gets visitors from me and one doesn't.

FWIW
