Again, agreed. But what when something is at the same time pretty much wrong but also something that everyone tries to do because superficially looks like a good idea? The reaction on StackOverflow was because they were getting dozens (hundreds) more or less identical copies of the same question. It was the same with "parse email via regexp" but I understand that more recent versions of the RFC make this doable.
