Terra, I happen to be a DM. I went out and bought all those damn 4th edition books the day they came out (goddamn pricey I'll add) and I plan to DM for a very long time to come. Know what the key to a successful campaign is? Keep the story moving along at a good pace so that things don't stagnate. Also, I'm an avid roleplayer, but that's about as geeky as I'll go into that bit.
I create character motivations and double crosses and little love interests and even the occasional silly twist. I can forgive that, that's fine, but I stand by my earlier assessment about the presentation.
