This is pretty much the same heuristic I use. I use Wikipedia a lot for obscure medievalist history topics, and those articles are usually very high-quality. But if you wander into a modern-day controversial topic, like "Palestine", it's going to be quite messy. You can even smell from the way an article is written that there's some trouble brewing in the Talk page.
