Twitter Hack - Techcrunch Ethics
While it might be entertaining to voice opinions on people ethics regarding the outing of the actual information, I think the real story is the lapse in security of the Twitter employee. A bad, guessable password was used to protect access to very sensitive internal data - but this raises an important point regarding the use of Google apps or any other easily accessible service.
It really shouldn't take an incident like this for companies to get these types of simple protections over their information. If there is risk related to disclosure of the information - make sure you have it protected.
