Sure they are interlinked, by your actions.
YOU are the first person to see a post or article when it's published, your IP address and time are logged thanks to any of the following - logged into Google, adsense on page, analytics on page, a search box on page etc.
When YOU next log into your Google account or your adsense account your IP is again recorded and, well there you have it, you told Google about all of your sites.
Solution? Unhook all Google products from your pages, don't use Chrome and don't use ANY plugin or 3rd party stuff on your site that might use Google products AS WELL AS don't use ANY browser addons that have toolbars Google can tap for information, which includes pagerank updates, Alexa stuff etc, etc. You can't even use Google.com to search with if "instant" is on because it pings google with each letter you type.
That won't stop Google from getting information from you via cookies or browser sniffing but it's a start. Google will eventually gather the data anyway from other sources such as tracking on your social network sites or from things like that little +1 button at the bottom of this page.
Post a new response? The +1 button at the bottom of this page knows the IP of the FIRST person to see the reply and they can match your WW forum ID to YOU when you next log into adsense or google or youtube or... you get the idea. Gathering data about you is a MEGA priority at Google.
