Does anybody know what EXACTLY was leaked? (Score 1)

Before Buzz was changed to suggest, instead of automatically follow, what information was jeopardized? Could somebody see your other contacts, your contacts email addresses, your location? I am not sure I understand what was actually leaked. I noticed in one of the links it says some woman's ex husband was able to find her location through Buzz. How is that possible and how could Google be so stupid! Someone please elaborate.
