Yesterday, Google released the New Google Toolbar Version 4 and with it came "Bookmarks."
Want to create and label bookmarks that you can access from any computer? Simply click the Toolbar’s star icon, or right-click the star to add and label a bookmark. You'll be able to access your Bookmarks menu on any computer with the new Google Toolbar installed. Note this feature stores your bookmarks online, so you’ll need to have a Google Account and be signed in to create and access your bookmarks. You can also view your bookmarks using your Google Account’s Search History feature. Just click the "Search History" link that appears in the upper right-hand corner of the Google homepage when you’re logged into your Google Account and you’ll see your Bookmarks
Aaron has a ThreadWatch entry describing these bookmarks and how they are displayed in your personalized results. Here is a quick screen shot from Aaron. Notice the new link under the results, I placed arrows pointing to them, those are the bookmarks...
But before you install this new toolbar, let's take a look at an old thread started by Bill Slawski back from Jun 18 2005 named If a Googler Offers you a Bookmark Manager, Punch Him. Long read, but he goes through how Google can use that data for personalized search and beyond. So when Bill heard about the new toolbar yesterday, he updated the thread saying, "I might hold off on this upgrade if I can."
