Why do we need the trilogy instead of just one site?
Why did you guys decide to arbitrarily partition off classes of questions into several disjoint websites? Wouldn't the tagging system have taken care of this automatically? IMO this was an absolutely terrible idea, because questions are far less likely to be answered if you have to bounce back and forth between several websites rather than having one centralized repository. Tagging questions appropriately is sufficient.
