Introduction and initial explanation: Hmmm, this is interesting, but sounds a bit lame.
Basic tutorials and walkthrough of Maven: Wow, this actually looks really awesome!
Advanced topics, explanations, etc: Seriously, that's how you're supposed to do that? That's awful! And what's up with that weird special case?
Really, it confirms my initial reaction -- if you play the maven way, things are pretty simple. If you try to do something weird, There be Dragons. I'm going to play with it a little more on a hobby project, but I'm not sold on it.
