The email I received from about my real-name being leaked was signed with "The Quora Team". That's kinda ironic, don't you think?

But still, it is not about finger pointing and blaming one individual. It is about a spokeperson for the public.

The guarantee that things will improve. Someone who will handle announcements and communications with the public and will vouch using their real name and reputation that things will improve. Someone who will explain what went wrong and what actions are taken to ensure this does not happen again. Employee training in place? Tier'ed access of data and information to employees. Stricter policies, eg you can't take a database backup home? etc etc.

Again, no crucifixation required, but pinning an identity can be good, because you know that there is someone and who that someone is that puts all their energy into fixing this mess.

Think of someone like Stamos at facebook. I don't know if his contribution in the end was a net positive or not, but it is good to know that there is someone that is focused on the issue.
