I saw this in Gizmodo's interview with Bill Gates when he was asked about RSS:
The phenomena for us is we've got in beta this MSN Spaces thing, and it lets you leverage everything you do around Messenger—that's your buddy lists and those relationships—to set up blogs, and who has access, and who gets notified. We've got up over a million people [who] set up blog sites.
I was writing my thoughts on that, but I got stuck after a few paragraphs and wasn't ready to wrap it up. So instead of that, I'll let you reflect on what Bill means instead of reading my thoughts. The key phrase here is "...it lets you leverage everything you do around Messenger".
