For JS-Kit’s part, and Echo specifically, the key is to ensure that a blog is a full and fruitful part of the full social media landscape. The goal is to make the blog post the first place to share a thought and the best place to see a complete and comprehensive view of the resulting conversation.
The conversation itself can and should happen on FriendFeed, Twitter, other Blogs, Facebook – you name it. These are natural, private conversations between friends. The blog author though, can enjoy the fruits of his work by watching the live reactions get re-assembled on his page.
It takes a bit to figure out folks. I will be working on modifications.
