I agree with #6, but it shouldn't always be geared towards the individual. You still need to think about the group as a whole sometimes.6. Know your audiance (players)
7. Use #6 to keep them involved - little things, like giving the only girl in the group a vorpal bunny because she's a Monty Python fan and likes small furry things. Sure, most of the time it does 1 dmg, but every once in a while it'll take a head off - and those times are precious.
For example, I don't like playing in games where things like vorpal bunnies are introduced. I certainly wouldn't use something like that in my own game regardless if a player would like it. As a player, I wouldn't care if another player is a Monty Python fan, if she got a vorpal bunny, I would not be ok with that. It's a hard situation to deal with & figure out how to juggle. Player A wants it, player B doesn't, so who does the DM cater to?

These points relate to what I mentioned earlier. I don't think not giving players what they want necessarily makes you a bad DM (or a better DM if you do give in).8. Give them what they want, but don't give it to them in the way they expect.
9. Give them what they want, but make them earn it.
10. Let them do what they want, but make sure there are consiquinces for doing what they want - sometimes, very, very bad consiquinces
If I'm trying to run a certain style of game with a setting that has a certain flavor to it, I don't think a DM needs to give players what they want if the DM doesn't want to. It may not make any sense for the PC to get what the player wants. The DM may also think what a player wants or wants to do is extremely lame and childish; which goes against the style of game he is trying to run.
Remember rules #1 & #2 (cause I agree with those). They apply to the rules I quoted above. If the DM says, "no" when a player wants something, then the player needs to deal with it.
(I should add that although I think the DM is always right, he can be wrong. I have no problem if a player questions the DM once about something. But whether or not the DM agrees, his answer is the right answer and the player should not argue about it.)
