Excellent post by danah boyd, reminding us that with social networks it all comes down to nurturing the network dynamics, not the technical features.

That’s the thing about social media. For people to devote their time and energy to helping enable vibrancy, they have to gain something from it. Something that makes them feel enriched and whole, something that gives them pleasure (even if at someone else’s pain). Social media doesn’t come to life through military tactics. It comes to life because people devote their energies into making it vibrant for those that are around them. And this ripples through networks.
