Twitter and Facebook

Twitter apparently is developing options for twitterers to make their tweets "private" - i.e. available only to their followers. OTOH, Facebook, which so far kept a user's status messages and other posts private, will now make them public, by default, if the user's profile is public. The user can change the preference to private. Looking at the posts on Facebook, one can see why the country is struggling- so many people wasting so much time posting absolutely inane stuff...
