I've included several links below that summarize the recent flap regarding Facebook and Robert Scoble. Many people are using this event to draw attention to issues related to data portability and to further their own cause. That's a mistake and merely clouds the immediate issue. Fundamentally, this is about understanding the terms of service of the social network sites that you belong to and honoring those policies. While what Scoble was doing was somewhat innocent (a debatable point), the media coverage would have been entirely different if the culprit was found to have been harvesting e-mail addresses and selling them to spammers or providing profile information to identify thieves (Experts: Security Flaws Vary on Social Networking Sites). Screen scraping to get around terms of service and/or the absence of desired program interfaces is a pretty weak justification to essentially hack the site's information ("the ends justifies the means").
Clearly there are valid issues concerning social network sites, data ownership and data portability but this scenario is a bad example for champions of a more open social graph to exploit. The debate remains worthwhile however - just without the Scoble scenario as a credible reference point.
Should Facebook allow its members to export profile and contact information?
Absolutely. But the capability needs to be implemented within the Facebook system in a manner that supports its terms of service, the privacy needs of its members and with controls that prevent wholesale harvesting of identity data.
