You have to have a Google account to use it.
According to the site you have to have above a particular version of FF or IE - what - no Chrome?
When you open the browser after installing the toolbar, the default page looks just like the Chrome default page - little thumbnails of "Most Visited" pages.
It directly competes with Digg, Delicious, etc and is will be much easier to use and more accessible.
It reminds me of panels like Quantcast, etc, that collect visitor data - over time, the Google sidewiki will enable Google Analytics users to marry up sidewiki data to their web analytics data.
If marketers thought they were losing the ability to control their brand because of user-generated content on Twitter, YouTube, Myspace, Facebook, etc - just wait........
