I vote to keep it. It's not like we get dozens of questions each day that need sorted out. It doesn't hurt anyone imo. Besides, if you remove it, people are likely going to post in 'general'.
If you want to talk about cleaning up, I'd rather choose to remove those older dx-wrapper categories. In fact, any category with the most recent post dating back to 2008 or earlier should be archived. Btw, with eliminating, you do mean archiving right?
