I really liked this article. I agree with most points. Point 8 gives me a little pause. Not because I disagree with the intent, but because sometimes too much error handling can cause more problems. What I mean is that sometimes allowing errors to happen in one part of the system will expose the true errors in another part of the system. As developers, we need to be aware of issues and then make good decisions about which need to be handled and which need to be seen to address bigger issues.
