The knowledge that you have to look at the newspage to avoid system outages only comes to you after you experienced such an outage. After getting mocked in the forums you'll surely learn that lesson.
But even then I had updates that broke my system because dependencies had been broken or the configurations weren't properly updated. And at that point you need to be an expert at every single software component you use. That is unfeasible for me.
Have a look at unthorty's reply. I would say that at least some of those errors could've happened to an experienced user.
