Google+ already driving traffic to sites

for now you have to get an invite from someone in it. what is your email? i'll send you an invite if you want one.

If I understand this correct Google+ is still in a test phase. Also someone told me that at the end of the test phase all accounts will be deleted for a fresh start when it becomes available for the general public. Maybe it's only everything you did in the test phase.

However, I couldn't find anything official about what would happen to accounts after the test phase. Does anyone have more information or a link? I just don't want to spend time building circles and whatever, only to get all stuff deleted when Google+ goes public.
