As you may have noticed, next to each article there is a DIGG icon. Digg.com is a social networking site which allows people to vote on articles that were useful to them. If you have found some of these articles particularly useful, click on the digg icon. At the moment, this is more of an experiment and depending on the response, the diggs will stay. We'll give it a month and see how this goes and hope this helps a greater number of the internet community.
