How private is your privacy on Facebook?

Yesterday I reported on a recent case that held a litigant had waived his attorney-client privilege by disclosing information by e-mail and in a blog. At least in part, this was because the e-mail and/or blog were considered a "public." Interestingly, I just saw a couple of stories about cases in which courts are allowing discovery of information posted online in "areas" thare are supposed to be more "private." Proving again, that there is nothing private on the internet, as one of the stories points out "increasingly, judges in civil cases are granting access to online caches that had formerly been considered off-limits."
