What is Lifehacker?
Lifehacker, the software and productivity guide, is a blog that covers tips and tricks for streamlining your life with computers (and sometimes without). Updated several times daily, Lifehacker points out software downloads, web sites, do-it-yourself projects, howto's, tutorials, shortcuts and tips for going beyond the default settings and getting things done in the most clever, unexpected and efficient ways. Think of Lifehacker as self-help for power users.
