I vote yes! I love Eberron, and while i recognize that a warforged adventure is little tough to convert to a standard greyhawk game, it's not impossible. And I really can't imagine anything more difficult than that. Most of the Eberron stuff is translated as easily as Forgotten Realms or Greyhawk. The only problems arise when you introduce races or character classes that don't exist in your standard world.... or should I say, that your players haven't encountered yet.
Do you use the Eberron content in Dungeon (or plan/want to use it in the future)? Sound off with a "yes," "no," or "other" and feel free to explain your choice.
My vote: yes.
Eberron is exciting, it's interesting. Not because it's new, but because it's genuinely well-designed and innovative. It's exotic, and yet distinctly and unmistakably D&D. It has it's flaws, like any setting, but on the whole it's very good.
Greyhawk is bland. It's dull. It tastes like chicken. This works as an advantage in one sense, in that a Greyhawk adventure can be seasoned and cooked and modified to fit into whatever world you like. But to convert a bland Greyhawk module into a distinctly Eberron one can often take a lot of work, with some complete re-writing necessary (I'm sure anyone trying to convert Shackled City knows this). Sometimes it's almost as easy to start from scratch. This is why Eberron adventures are needed.
