I understand. That's bound to happen anytime people request major features; coming up with cool new ideas is one thing, implementing them is quite another.

However, it's among the most popular feature requests I've noticed so far. Having themed subreddits would improve functionality for many users, and I'm not even talking about the specific suggestion in cleonid's comment. How many hours/days of coding or testing are we talking about?
