Shylock Adsense Wordpress Plugin
Shylock Adsense is a WordPress plugin that allows you to insert Adsense ads on your blog without modifying the template. More then that, you can set it up to show different Adsense ads for articles older then X days (x is the number of days you decide).
For example, you can insert a 468×60 ad at the bottom of a new article, and once that article turns 7 days old it will have a 336×280 ad blended with the text from the beginning of that article.
