Google launched a new service called Sidewiki Google, a new feature in the Google Toolbar for Internet Explorer and Firefox. With Sidewiki visitors can add a page more information.
To use Sidewiki, make sure you have installed the latest toolbar (version for Firefox 6.1, Internet Explorer 6.3), and a Google Account. With the help of Sidewiki users can share knowledge and experience with users from around the world. You can write comments, share knowledge and communicate additional information when you visit different web sites. All they need do is open the sidebar on the left of the browser window. The contributions are visible to other users and help them to find desired content quickly.

People with a website always have the option to exclude page editor to write a note which is always the first note to the page in question appears. They should be claimed through the website webmaster center.
Notes can be seen when you go to Google.com for example, when you visit the homepage is in the browser pane on the left side of the screen that you can collapse the comments placed to view. The Wiki Side button in the toolbar is also yellow when there are notes available. The button remains white if no notes are available but can be placed. When you visit pages for which no notes could be placed the button turns gray.
