HTML5

I really like new ideas. There is nothing more exciting for me than getting a new specification of whatever and study it.
But. Previous "But" denotes somehow "Hm. I really don't know" or "I'm sorry, I'm not sure". Hesitation multiplied by million.
I have to verify my sources. w3.org, whatwg.org, mozilla.org. Serious players? And still no clue what HTML5 is for. Few tricky features. Nice, but I don't need any HTML5 to create the same type of content and functionality.
"Tag soup". In many places I've found such a "definition". Well... Another "But". Probably authors doesn't see the difference between complexity and an ordinary mess. It's like saying that billboards are better than books because billboards are more readable.
Anyway - will see the future.  My prediction for HTML5 - it doesn't make any sense now. Maybe the future 'll show I'm wrong. Maybe.
