How much information can Google accumulate about you if if just block Google cookies? Even just using session cookies and not loggin in to Google should be enough).

Its more of an issue here because we have more reason to use Google services (Webmaster Tools,Adsense, etc.), but the only Google service that requires logging in that is widely used is Gmail (the last time I saw market share numbers it was still less widely used than Hotmail or Yahoo Mail).
