Will facebook self destruct?

“Columnist Cory Doctorow describes how Facebook and other social networks have built-in self-destructs: They make it easy for you to be found by the people youre looking to avoid.”
While I have been lucky so far and avoided all facebook stalkers (no this isn’t an invite!), it seems that there are some (and Cory is not just any some…he is a pretty smart dude) who think that Facebook contains the means of its own destruction.  Maybe that’s why we all like it…it’s kind of like us.
