I had to stop reading when I got to the ridiculous header example. A poorly set up header hierarchy is used to show why the new way is more complicate? The new way is much more flexible when used properly. If it is too technical for some non-technical people, those aren't the people that should be writing HTML.
The fact that the new article and section elements can now have their own header hierarchy doesn't mean we should "use only one heading element (h1...)". The beauty isn't that we don't have to think about the hierarchy anymore but that now each distinct "document" on the page can have it's own h1-hn hierarchy.
The problem is that the subheading in my articles is really part of the main heading. Without it the heading itself loses meaning. When using the hgroup tag only the main title is considered for the document outline so I'm losing valuable information there. As for the fix, I'd rather split both titles in the h1 tag itself. That way both titles remain 1 whole, even for the document outline.
I've actually found myself moving in the opposite direction of integrating the social media stuffs. Now I visit the sites if I want to check up on things or post something. Requires more effort but that keeps me from wasting too much time with it.
Using virtual currency that you can earn in-game, but also purchase with real money, seems like a great idea. The users don't feel like you're hiding the good stuff behind a paywall, but you still give them a way to pay for it if they want to. I like it and I'm glad to see it could actually work.
