Ever-since we got a sneak peak at Diigo, I've been playing around with it and marveling at the latest feature releases. Diigo is the product of hardwork, deep understanding of what end users want, and one of the most feature complete social annotation services I know of. Last week, the team at Diigo released some great updates that make it all the better reason to switch from whatever social bookmarking tool you're using, to Diigo. Here's a rough outline of what the team has been up to:Easier to Bookmark: Recent updates allows users to add a 'Diigolet' to their bookmarks; a button that allows you to add whatever page you are viewing to your Diigo bookmarks, an invaluable tool for information hungry users.Importing/Exporting: Badges are the 'hip' thing right now and Diigo doesn't want to miss out on it. So, they will be releasing a linkroll that will allow users to add their recent bookmarks to their blogs or websites to share what they have been bookmarking. You can also import your Del.icio.us bookmarks to your Diigo account.Toolbars: The Diigo toolbar has also been upgraded. You can blog about the page you are viewing with the "Blog-This" button, as well as instantaneously add the page you are viewing to your bookmarks.
