To Digg or not to Digg? That’s a good question. Digg is a popular online social bookmarking site where you can digg or bury–rate an online article, video or podcast thumbs up or thumbs down. Submit what you like for other members to find. The more diggs it receives, the more popular it gets and the higher it comes up on top of the page heap. This is one place where your reactions are valued. Digg lets you visualize the content and participate in a number of ways. That’s the social part of it, aside from letting you find out what your friends are digging. Members can also customize their view to remove categories they are not interested in. But even if you don’t sign in, you can find out what diggers are discovering.
