Google Sidewiki was introduced a month ago as a new way of contributing helpful information to any webpage. Google Sidewiki appears as a browser sidebar, where you can read and write entries along the side of the page. A lot of great Sidewiki entries have since been written throughout the web -- a few of my favorite examples include a doctor's entry about flu vaccinations and these tips for tuning bass guitars.
Until now, Sidewiki was available only through Google Toolbar for Firefox and Internet Explorer. Today, we're excited to release the official bookmarklet for Sidewiki, which lets you easily read and write Sidewiki entries in Google Chrome, Safari and others browsers. The bookmarklet is a shortcut you can add to your bookmarks bar: When you click on the shortcut, it opens a window showing Sidewiki entries for the page you're currently viewing.
To add the Sidewiki bookmarklet, all you need to do is click and drag the bookmarklet embedded in the Google Sidewiki Help Center page to your bookmarks bar.
