Robert Scoble just put up a long and detailed post about the idea of ‘Malleable’ social graphs and minimobs. A malleable social graph is one that “changes based on conditions you set in motion.” Providing a number of examples Scoble talks about how an ideal malleable social graph would change based on where we are, what we’re doing or what we believe. And this element of Relevance is exactly what Facebook and Twitter have been lacking so far.
