Apparently, just as Google Desktop Search, Google’s new browser, „Chrome“, has a unique ID. That basically means that if you are using chrome with any other Google service, like GMail, Google will be able to create a personalised history of browsing. According to Golem.de, Google say they don’t that. But they could. Easily. If you don’t want that, and there are important, very important reasons not to want it, don’t use Google chrome unless Google changes this ID policy. I will only use it locally to ensure cross browser compatibility for my webpages if it gains some non-trivial market-share. Luckily, the layout engine is based on WebKit, so there won’t be too many bad surprises in that respect.
