"You should only ask practical, answerable questions based on actual problems that you face. Chatty, open-ended questions diminish the usefulness of our site and push other questions off the front page." (FAQ's bold)
However I don't feel this is actually conducive to a useful GIS.SE. If you look at the list of Highest Voted Questions you'll see that the vast majority of them are actual subjective discussion questions with no "right" answer nor in many cases even a "practical" one.
I appreciate there is a large subjective element, but given so many of GIS.SE's users find these questions useful (see the upvotes) I suggest the FAQ should be updated to reflect this.
Sure there's probably only one sensible to way programmatically set polygon feature fill colors and outline in ArcGIS (to pick one randomly), but that sort of question is only one small aspect of GIS. Much of GIS is subjective and doesn't have such clear cut solutions, not just the cartography aspect, but even analyses themselves, for example, when choosing which tool should be used for a Classification or how to pick a coordinate system.
