Google adds “Note this” option on Google Search Results
If you are logged in into any Google Service such as GMail or Google Notebook or Google Analytics or any other service from Google and then visit Google.com and enter a search query, you will see the “Note this” option button beside the Cached and Similar Pages option.

Once, you click on “Note this” option near your search result, you see a “Duly noted” option.

Now, if you wish to see these snippets or rather search results you have been saving, you can log on to your Google Notebook account. There you will be able to see all the google search results you might have been saving. In your Google Notebook, a link to the site and a brief description of the URL you just noted will show up. Here, you can add a comment, and also change the URL of the site you just saved. If you wish to add notes from any webpage on the internet, you can download this browser extension provided by Google

While this might not result in the death of social bookmarking, this is definitely a very cool way to store your search results from Google.
