Fred, with all due respect, there's almost no way to centralize the conversation anymore. Twitter, FriendFeed, Social Media, Digg, Hacker News...it has spread the conversation to many, many corners so people in many niches can discuss what's going on.

Yes, in an ideal world, the conversation would happen in one place (that's part of why I think Disqus was a great investment and FriendFeed is destined for greatness), but this is a fragmented world and fragmented conversations are going to always be a part of the world's dynamic.
