When does the public beta phase begin?

Question

I think it was supposed to start a week after private beta opened. It's been about that long. When does public beta open or has it already?

Answer 1

In about two hours (as of this post). By time you read this, the public beta will have likely already started. Public beta starts 7 days after launch. For reference, you can always track a site's progress in Area 51 (http://area51.stackexchange.com).
