Folkd is a combination of social bookmarking, Digg-like voting, notes and recommendations. It works as a browser extension which you can download through Mozilla or on site.
Folkd culls tags, comments, podcasts, and other informative bits and links them to web pages and topics. Once the extension is installed a tabbed sidebar displays this related information. Users can vote up sites with the Folk it button. There’s a panel for viewing your friends folkd pages. The save it button allows users to add tags or keywords to certain items. Count in media support (you can upload and listen to music and watch videos), notes, international language support, and action tags too. The site also has live chat and audio recording to add your own commentary to sites and themes.
