If that's a comment you get, write better code. It does not matter to me whether closing p-tags is mandatory or optional. If you don't do it, I don't want you working on the same code base as me.

This kind of knowledge makes for fun blog posts, but if people direct these kind of comments to me. You're obviously using your knowledge to just patronize and lecture people.
