Same here. I think the return to "do whatever you want and we try to interpret it correctly" was wrong. Code in XHTML is way more readable, maintainable and easier to learn (IMO).
I still write my HTML5 in correct XHTML Syntax.

Sure, you save some (or a great deal many) characters, but at the cost of making everything that needs to work with it more complex. (Browsers are a large slice of this pie, but by no means is the only slice.)
I'm going to sit back and wait for the cycle to come back around to XHTML-like correctness again.
Those who cannot remember the past are condemned to repeat it.
