No option for me, so I didn't vote. I play, I DM, and I like the idea of skill challenges but won't know for sure until I can read the system; I want something substantial, not a one-page 'you can roll skills for stuff' throw-away.
I am yet another person who both play and DMs, and I like the skill challenge system based on what I know about it. It just seems like it will make things more interesting and fun.
Love the system. It's not a necessary thing as many have pointed out, but it's really nice structure to have for both newbie and moderately-experienced DMs. Not to mention the fact that play goes a lot faster when players actually know the basic structure of play as well as the GM. Then the group can get on with playing D&D instead of playing that other fun, fun game we're all familiar with, 'Read the GM's mind'.
