John Naughton is spot on about the recent Facebook announcements in his Observer column:
What’s comical about this stuff is not so much its implicit arrogance – the assumption that we all want to share using Facebook – as its historical naivety.

Repeat after me: the net is bigger than any single enterprise. And nobody owns it.
Well worth reading in full.
