Brad, please reinvent blogging. I imagine that a "next-generation blog" (NGB) can both publish your own posts and receive your friends' blog posts (like receiving an email), so that they function like a virtual, decentralized social network.
For example, there are two people, Alice and Bob, and their NGB accounts are:
Alice can share with Bob by adding Bob's NGB address to a "circle" of hers in her NGB user interface. If Bob accepts that sharing, every time Alice creates a new post in that circle, Alice's NGB server (ngb.google.com
) will send that post to Bob's NGB server (ngb.microsoft.com
), and that post will show up in Bob's incoming stream in near real-time.
