YouTube joins Facebook in the very exclusive billion monthly user club

Google announced today that YouTube now has over a billion unique visitors every single month. Which means that Google and Facebook have something very rare in common: both have a billion-person social network.

One billion smartphones? Well, yes, it’s coming (of course)

In other breathlessly breaking news, Facebook will top two billion users, probably two years from now. Google's website index will reach a trillion webpages, about two decades from now. And the sun will likely go nova, if we're still here in a few billion years.
