Social Noise
I brought up something in my last post about friend/follow relationships that I think deserves more attention than I gave it: the social graph -- as it is currently constructed at least, where all relationships are equal and mean the same thing -- is not the same thing as an interest graph. The implication is that using a standard unweighted relationship network to predict what content should show up in my activity stream will result in me seeing a lot of content that I'm not really interested in. That's inconvenient at best. As Hunter Walk so charmingly put it, "I like you, but not everything about you."
