When I go to a category I see a couple of recent questions, then only questions from a week ago. What is wrong?

They've got a bug. The guys with high foreheads and thick glasses may be able to figure it out. They may not. I suspect scaling problems, but that's an opinion. "Scaling" means something works fine with 100,000 records but bogs down when that number increases 1,000-fold.

I think they are just in some kind of order for the categories. Maybe there aren't enough new questions coming in. Go to All Categories and scroll down. Those are all new questions and you can choose which ones that interest you. I had noticed that , too.

There is a glitch with Yahoo Answers right now. The site isn't loading properly.

That is a bug that pops up from time to time.
