I see this as useful for folks who want to run their own independent blogs — and then aggregate the sum of the parts in a metablog. Remember the Five Lives project I wanted to do, Joe? A Geek Cereal-like group journal with a different person/place/life every day. This could facilitate that much more easily than we would’ve been able to do it those years ago.

I don’t see a point in using this for folks you don’t know, but as affinity groups and tribes continue to develop online, I think we’ll see more and more groupblogs compiling multiple independent blogs. You can read who you like — or you can read the gang.
