Google today launches its Web History feature that allows you to track your all your web activity with the simple addition of a Google account and the Google Toolbar. So you will now give even more of your life to the engine that is out to know everything about you, with your web history, your email, your blogging history and your click streams. Decide how much of your attention stream you wish to share. You can pause the data collection but it may be easier to have 2 browsers.

However, one interesting thing that is there is the ability to export your attention stream, to take it out of Google via RSS, so you should be able to grab it and move it elsewhere, to analyse it or to feed it into another tool. Google will also analyse it for you.

Good and bad – you can track you activity and use it for whatever you need. But so can Google.
