http://www.theadsensegame.com/ Joel Comm has released the first ever Adsense game. The game lets you pick your website type, how you plan to build the site, type of marketing, ad types and ad placement. The game then lets you see your results day-by-day.
Joel Comm is a great guy. It's Bush who should be called the sleazebag. But lets not go there with politics.
I think Joel's niche for his ebooks are AdSense beginners who don't know the program jet and did never hear about it. If you are already using AdSense and know a little about ads positioning, blending,... than his ebooks are definitely not for you. One day browsing this great forum will give you more info and tips than all Joel's ebooks. All after all Joel is doing a great job in self promoting.
It made the digg front page aswell, over a thousand sales at least with all the attention combined. (from the game not altogether i dont mean)
Who wants to practice? Time spent practising a game is time wasted creating content, link building, SEO, etc.
