Check out this quick demo video about Diigo v3 and find out just what it can do. Please note though, this video surprisingly showcased a screen-shot of TechCrunch and not SOMEWHAT FRANK - there must be some sort of mix up. :) Nonetheless, Diigo v3 is pretty impressive. I like the way that Diigo enables users to create lists of bookmarks that can then be viewed a number of different ways (list views, web slide view, etc). I also like its bookmarking toolset as it offers a number of innovative ways to capture and annotate content.
