> You can make your email private in Facebook and you do not have to friend people. I would argue for a downloadable list of contacts/email address whose emails you have access to. Facebook already allows hotmail+yahoo access to the email lists, the individual user can not download it directly.
I friend people based on the assumption that they can't export my email to arbitrary third parties (which is true at the moment). If this is no longer true I would delete all my friends, sue facebook, and meet friends in person to socialize. But the other thing you mention is reasonable. But it would have to be opt-in since by default I don't think people would want this. Also since originally signing up this feature was not implied.
