I think the topic of Gilmor is a bit different, because he was basically saying FriendFeed sucks, without having ever really using it. So how could he evaluate it without fully exploring the service?

Other than that, I would agree that we all use social media in different ways, and not all of us are about the conversation. Value is something that differs from individual to individual.

In regards to the echo chamber, I agree that it is what you make it. Which leads me to believe that we are wasting our time complaining about the echo. We need to encourage and appreciate new thought while mixing up our own personal networks.

Charlie Anzman gave a good suggestion yesterday: picking up people off the Everyone tab in FriendFeed. I think it's a much better way to hear new voices than just using FOAF.
