You would have to come up with one of those color coded test first: you are a green DM, or a red one, or a blue...Once that is done you will know what direction to go to.

To do so would be like a moderately successful author to go around asking his average reader how to improve his wirting style. It may yield some interest like/dislike info on his reader-audience but won't yield a qualified opinion, that's what the experienced and qualified editor is for.
This is true...player will say they are having a good time but their actions say different and what they say away from the table can be harsh.Psion said:Well, I rather think the thing here is that players are experts in what they like and don't like in a game. So at least you can glean that.
I think the problem is that it's real difficult to get honest and useful feedback from players.
