Yeah... I've heard of that site. They tell me it's a pretty good place to go and learn something. ;)
Here are just 3 of the many useful links I have bookmarked:
http://www.yolinux.com/ --> for tutorials.
http://www.linuxquestions.org/ --> helped me when I first started with Linux. Searching this site still continues to be helpful.
http://www.linuxhomepage.com/ --> seems like almost everything has a link here.
