Private - what?

There was a nice article in today's WSJ about how IMs (Instant messages) can haunt you. If you thought IM is a good place for private chatter, think twice. A lot of these messages (including Google talk) are saved automatically (unless you specifically disable the setting). So, if you think you are having a private conversation out there, think twice... Not sure how this posting is related to web 2.0 but thought I will post anyways :)
