Facebook has allowed you to stay in touch with more than just your close day to day friends. It has given you the power to track and keep in touch with your whole friendship ecosystem. It allows you to keep in touch with everyone from your best friends to the person you met a conference once to your long lost friend from third grade.
The thing is for the most part all of the relationships are seen as the same in Facebook. This makes it incredibly hard to filter out the noise and just hear the signal because you have this constant stream of everyone’s activity.
Robert Scoble has very elequently stated in some recent videos how Facebook knows who you’re close to. They can tell you interact with, message, poke, attend events, went to school with and so on. You think they could put in some type of automatic filter that allowed me to see my close friends more prominently then the person from the the conference who I don’t really talk to or know that well. The thing is… they don’t have this feature.
Facebook should be using all of this activity and attention data to shape how we see the dat that is being presented to us.
Right now there is a Facebook Application where you can choose who your “Top Friends” are (which I still think is a dumb idea). I’d love to see an application which would show you who your top friends are purely based on the history of all your interactions on Facebook.
