I wonder if KQ could provide more articles that are system neutral, followed by a 4E and 3E component. A monster article, a set of traps, etc. I realize that authors usually speak just one language (I'm happy to create a 4E monster but I won't go back to designing 3E ones, someone else might feel the opposite), but there could be a stable of writers that would take on the task for a low cost (and high benefit to the reader).
