Clay Shirky is "guestblogging" on the side bar of boing boing this week, and starts out with this great line:
I'm obsessed with social software these days. In the Before Time (<=1994), the standard internet tools like usenet and mailing lists were inherently social, but on most of the Web, the height of interaction was one-click ordering. So I'm thrilled whenever I see anything actually making real conversation possible. Particularly interesting is the way the blogosphere is becoming an inside-out usenet, with the content centralized and the namespace distributed, instead of the other way around.
Nice.
