Mostly because I always wanted to run a pen&paper rpg, even though I am fairly busy, and this provided a rule-light enough framework to just do that. Especially Vornheim, that shows how to do randomize world building in under a minute :-)
I love Dungeon World with all my heart. I'm a newbie GM as well, and it's the first game I ever ran (like a year and a half ago).
I love the philosophical approach it takes to the game --a rules-light, minimal-prep collaboration between the GM and the players. One of the core principles for the GM is "Ask questions, use the answers", which is wonderful to me. In a couple different games I ran of DW, we started with just the player's character choices, and the questions I decided to ask, and got rolling from there.
For anyone interested--the rules are free on their website, and there's a thriving G+ community, "Dungeon World Tavern" (can't link it at work) with very creative people. Also, the "Indigo Galleon" adventure, from the DW website, is my favorite, and a good place to start. It was the first thing I GM'd, and I'll be running it for a third time next Wednesday.
If anyone's looking at it and has questions, let me know --I love seeing people get into this game (or pen-and-paper RPGs in general).
