I'd like to start something called a “Namecrime Exodus”; if by September 10th Google are still forcing people to use real names, I'm leaving Google+ and deleting my account.
I strongly encourage you to post likewise and commit to leaving a defective service that doesn't understand or want to understand the freedoms and cultures of the internet. Google is a company born of and dependent upon the internet and the people who use it. In a dawning era of P2P culture and infrastructure, Google should know that they cannot afford to alienate their customers.
You can find me on Twitter @onetruecathal, so I don't see why I'd bother tolerating another social network if it means violating my principals.
