Analysts have been starting to look at the details of last week's sale of Friendfeed to social notworking site Facebook and are worried about what they find. The deal cost $47.5 million but it puts Facebook in an incredibly powerful position.

FriendFeed is an obscure social-media platform that acts as a clearinghouse for all of your social-media activities. FriendFeed everything you do online and tells it to the world. So if I post an article on my blog, Friendfeed will tell all my Facebook friends. It also tells me what they are doing. It does have limitations but it does put Facebook in an incredible position of control over lots of rival's antics.

Some of this will enable Facebook to make real-time searches and provide competition with Twitter however it will also place Facebook so it could control your social life. Right now the majority of your news feed is filled with updates that your friends have which are internal to Facebook.

However with a mashed up aggregator you can find out what everyone is doing outside the social notworking site. But ultimately it will drive you back to Facebook. Facebook becomes the one portal to rule them all and in the darkness bind them.
