They are all new, recently-added categories on WikiAnswers.
The beautiful thing about categories on WikiAnswers is that anyone – even you – (yes, you!) – can put on the big boy boots, take the reigns and suggest a category based on your interest, popularity of the topic, etc. You can make it happen. And I’m pretty sure that’s what Uncle Sam was really saying when he said that stuff about you.
Check out the current category list. Don’t forget to check the drill-down arrows for further levels of category goodness. Check out the latest categories on the What’s New page.
