These are links I use most often:
www.lifehacker.com – Lifehacker is a great site to learn how to get the most out of technology and everyday things.
www.jalopnik.com – A great automotive enthusiast site. This place has interesting articles about new vehicles along with great pictures.
www.xbmc.org – XBMC is simply the best front end media center you will ever see or use. It runs on a number of platforms, is easy to setup and use, and best of all, is free!
