New Resolution - Pick up Distributed Version Control

I'm starting with Mercurial, because Joel Spolsky wrote a tutorial on it. I admit I had a hard time trying to pick up Git and Perforce (is that a DVCS?), but I am starting with Mercurial.

I've just started on the first chapter at hginit.com.

Mercurial is a modern, open source, distributed version control system, and a compelling upgrade from older systems like Subversion. In this user-friendly, six-part tutorial, Joel Spolsky teaches you the key concepts.
