The Washington Post opens its article about FaceBook's purchase of FriendFeed by saying "Facebook just bought the rights to nearly everything you do online. And it cost them only $47.5 million."
Given that FriendFeed offers a technology to aggregate all of your content and distributes it everywhere and the FaceBook user agreement gives them the right to your content, including to monetize it, you have now lost all rights to control and monetize your personal content on the all social network sites - not just Facebook.
Of course there is no way sports and entertainment rightsholders are going to license their content to fans (as I proposed here) for a reasonable price if FaceBook will then have the right to monetize their content mashed with your personal content.
Yikes. Isn't one of the downsides to the FREE/Ad supported b'ness model the tendancy to find one's self at odds with your consumers? Doesn't the AP digital wrapper have more upside for consumers than Facebook's approach?
