...programs. they should give more space for the title. I'd say Google Adsense is the most over rated for all of the well known ones. It has the name Google, that's probably why its talked about and sought so much. A lot of people complain about Amazon being not sufficient due the cookies only lasting 24 hours and its low commission rate. The fact that its such a trusted site with so many things makes such a short cookie duration justified, in my opinion. So if amazon's cookie lasted a week or more that would be too good to be true. It would be "too easy" to make money off of Amazon, and amazon affiliate links would probably be spammed a lot more. Amazon might even lose money as a result.
