Digg is another site that is based on the bookmarking concept. Here one can create a profile and submit content – articles, video, a podcast etc, which would then be given a thumbs up(’Digg it’) or thumbs down(’Bury’) by other Diggers. Depending on how popular your submission is, you can come out tops in the respective category and see your submission in the ‘Newly popular’, ‘Top in 24 hours’, ‘7 days’, ‘30 days’ or ‘365 days’ popularity charts. They also have a visualization tool with which you can track your submission’s ‘walk to fame n glory’ or …. .
The way Digg has it on their site: “Digg is a digital media democracy. As a user, you participate in determining all site content by discovering, selecting, sharing, and discussing the news, videos, and podcasts that appeal to you.” This site sure is one of the most used and popular ones. A very clever invention. I WILL have my own login!
