I feel like General is not a really helpful category on Meta. It holds 200 something topics right now, but looking through them many would actually fit right into Site Feedback, Feature or Support.
I think cleaning up the category would only leave maybe around 50 topics that indeed don’t belong anywhere else. And for these topics a more specific category title could make better sense (like Off-topic, Random Talk, Watercooler, …), rather than General.
