Anonymous, the loose collective of hackers, activists, and troublemakers were prohibited from making a news group on Google+. So they're gonna build their own social network. So much for being anonymous?

It seems that they're looking to make a place that's censorship-free for disseminating information. Well, why not host a blog? Or use Twitter, which seemed content to let LulzSec release password dumps via the service.
