Except in one sense, it already does.

I have some friends with blogs. Those blogs have RSS feeds. Feeds of "news", you might say.

I load up sageRSS in Firefox, see friends who have new content in bold, and get their news. A "news feed", you might even say.

Admittedly I can't easily use that to deduce that x is friends with y is friends with z, or (easily) get a map of where all of my friends went on vacation last year, but I kind of think that's a good thing.

this is kind of dying though, or at least flat in terms of growth overall
