GTD in a Nutshell

I found this really cool post that explain (practically) everything about GTD.

I get a lot of email about Getting Things Done (GTD), mostly from people just starting out who have various questions about implementation, starting out, or sticking to the system. I thought I’d start a FAQ to help those with similar questions.

Also, if you're looking for some software to help you with GTD, you should read this post from the same site.
