Google have updated its algorithm from June but only in USA. I actually did not know about it but you can read about and much more on this search optimization blog. I found many thing very interesting on the blog, like the video from Matt Cutts.
If you like to make money with your website they also have a section for website revenue and affiliate websites. There is also an interesting article about paid links and how to avoid being banned by Google when you buy or sell links.

Google Adsense will close the Google Adsense affiliate program that has not given me any money way but maybe other will feel the pinch.

I think it has played out its role because most people know what Google Adsense is now anyway and Google Adsense can not control all the people sign up they have no way to check the different names and addresses.

So it is time to get your favorite coder and ask them to take away all the referral codes you have on the website.

Nothing will happen if you not take it away but you will not get paid for any referrals after August 2008. If you for some reason need the statistic you need to download it because it will also be deleted from the accounts.
