Stub of: This would be a very stupid idea without AI
VGR's post is about how AI might be able to make chatty, wild, multidimensional conversations across websites legible to humans because each user of a network (such as Blygger) can create their own interfaces. I've been thinking about this for Blynger in a medium-term way, but it's too early to worry about now because Blygger only has a few users right now.
But yes, one area I think will be fun to explore is new ways of rendering the reader. Like using your blogroll and your private subscriptions to help curate a feed of responses that you most want to see in a wide-ranging conversation.
For example, if everyone publishes their blogroll, then the AI could know that even if I don't follow a given feed, I might possibly want to see a response on it in a conversation I am following from someone if they are on the blogroll of a feed I do follow. That kind of thing.
