Dragdis - a visual bookmarking tool
Very clever and well implemented. You should try it.
The main problem with most bookmarking tools is that you either need to do a lot of actions to save anything or you end up with a huge clutter later. Dragdis solves all this by allowing you to drag and drop links, images, videos and text to folders that appear on the right side of your browser the moment you start dragging something. With two full days of Dragdis behind me, I am a very happy user as links and smaller pieces of content ar organized and easily shareable.
