I think Adfly would work on certain types of websites, but from my experience, it only ever works with sites that have a less mainstream function. If someone were to want to read up about his or her favorite TV show through a blog, I doubt he or she would put up with Adfly. But if it were a guy looking for sexy pictures, then he probably wouldn't mind clicking on it just to get what he is looking for. In my opinion, if you can come up with a unique system or could offer unique content that people would really search out, then Adfly can work great, otherwise it's just too much trouble to try and get 10,000 views just for $5.
