We'd say Netflix had launched YASN (Yet Another Social Network), except for that fact that sharing movie lists with friends and like-minded folk is such an obviously good idea (so long as we can hide all the porn). So when we heard that Netflix's latest strike in the bloody battle with Blockbuster was to launch an invite-only Friends list where friends could share movies and rank them with little purple people icons, we had to take a look. As Hacking Netflix and others have said, it's pretty neat. Only we're still figuring out how to hide the porn. Any tips?
