It's worse than that, there's pretty much no effective way to use the site to learn about a topic. It's a very effective Q&A site but that's all it is; it was meant to be slightly more but has never managed to achieve that. I'd say there's a very big opportunity in there for anyone who wants to try to compete.

Actually, I've used Stack Overflow to learn things by trying answering questions I don't know much about. Most of the time I don't succeed in answering them, but I always find out a lot while trying to research/figure it out.
