One problem is that we are already confronting a possible natural limit in the number of questions that there out there. Now I'm sure that there are more than 500 reasonable questions about bikes and cycling, but there is going to be a vastly lower limit than, say, on parenting, ubuntu or web applications.
This is not advocating an acceptance of more forum-style debates, but we should as a group (and specifically those of us with +500 privileges) be a little less quick to close. I'm especially thinking about the fairly short shriftfairly short shrift that particularly local/regional questions are given.
On my commute I can think of several peculiarly local questions, but I doubt they'd stay open for long.
