Thanks to Plurk and Marhgil Macuha because if not for those two, I wouldn’t know that TODAY is the deadline for a new requirement of Google Adsense:

In preparation for interest-based advertising, please ensure that your site’s privacy policy is up to date by April 8, 2009. Visitation information from publisher sites will be used to create user interest categories, delivering more relevant ads and improving monetization for publishers over time. Learn more…

I need not say more, JUST UPDATE YOUR SITE with PRIVACY POLICY NOW!

You could take a look at JenSense for some examples.
