True, for source code it might be better to leave those in. However, the fact that omitting them is standard-compliant is interesting for automated minimizers.

Yep I agree with that top comment. Explicit is far more understandable and maintainable than implicit.

I tried this for a summer, it really did lead to easier to read HTML... although now when I go back I’m not sure which tags can be omitted and which might be errors. I think it’s probably a net negative trade off but still not certain.

These days Im trying out pug instead, which is similar in a sense: more concise and readable at the expense of other people being certain of its correctness and myself remembering the syntax months later.
