Mostly to be consistent with "HTML5".

It's longer, and it's not clear to me that people are actually confused  
about what "HTML4" refers to.

>> "Modern HTML differences from HTML4"? I'm not convinced that's a win.
>> "Near-future" seems wrong since it's more like "current".

Here "HTML5" is supposed to refer to "W3C HTML5 and W3C HTML5.1"?

How about I go back to the original title "Differences from HTML4"?

It's more intended to be an overview. Can you give an example of something  
that is too detailed and suggest the level of detail that would be more

Thanks, that's useful feedback.
