Free Software Daily is a very good site. It features a lot of articles that deal with Linux and free software. There is information for beginners, intermediate and professionals. It is a good site to learn about new and old issues concerning the free software community. You can read the articles or register and vote for them. The concept is similar to Digg. However, Digg is not as it used to be in the past. There are much fewer technology articles dugg. Fsdaily focuses more on technology, open source and free software.
