While most Linux operating systems come with their graphical user interface it sometimes is still important to work from the command line, especially if that is the only way to access a Linux server. Linux Command Line Fu is a Digg-like website that lives of its user contributions. Users can submit and vote for Linux command line gems.
Each submitted Linux command - to be honest there are a few command submissions for other operating systems but the majority is pure Linux - lists the command itself and a description provided by the author of the command. There will also be information about the author, the date the Linux command has been submitted and the amount of votes that it received.
Logged in users can vote, leave comments or report a command as malicious. Command-Line Fu can be accessed with an Open ID.
The site features a search engine and will also post new commands submitted to the site to a Twitter account. The site would do good to provide a list of all available commands to print it or save it in a text document format. It is still a very interesting resource for Linux users who work with the Linux command line regularly.
Update: The site is interestingly enough still up and running on the Internet. Commands seem to be added frequently to the site, so that you can still learn a thing or two if you visit it frequently to check out what's new. I do not really think the Digg-like system works for a site like that, considering that your interests may be totally different from what the majority is interested in. Still, if you are a Linux beginner it may be a good idea to check out the site to get accustomed to some of the more popular command line options you have available.
