"Over the last month I've started using Diigo as my primary tool for bookmarking links. Yesterday, Diigo released a new version of their browser extension. The updated extension includes some features that are quite handy.
The most significant of the updates is a streamlined screenshot process. Now you can click the browser extension to take a screenshot of the page that you're viewing. "
"Diigo stands for "Digest of Internet Information, Groups and Other stuff." It is a social bookmarking program that allows you to save your 'favourites' online, so that they can be accessible from any computer with an internet connection. However, Diigo does much more than this."
