Dialing 911 in the EU can redirect you to 112, though I don't know how that redirection works. It's worth knowing the local emergency numbers in any case
I think Pinboard is more likely to buy Twitter. And honestly this might not be the worst thing that could happen to it. Not sure if Maciej will be keen however.
In the context of a replacement for Hollywood by something new, most likely something new on the internet, why would anyone bother to restrict the market to a specific region ?
My comment wasn't about technical feasibility, it was more about the fact that, by default, the web is a planetary medium, therefore, any new entertainment made on it is available without regional restriction unless the authors take steps to create such restrictions.
It's obvious that many new forms of entertainment will use the web as a medium which, barring dictatorships, is worldwide, so you don't have to worry about it, insofar as you have enough bandwidth.
