distributed twitter

an advantage to twitter's downtime is that is causes developer-types to think about how to make the activity stream that we all like to be more distributed and therefore more reliable.

local activity stream manager/filter/aggregator.

   configure your home page URL.
   pick up XFN friend links from home page.
   build RSS feed list from friend links that have meta tag for RSS feed.
   also take manual RSS feed inputs.

   order friends list by importance (add importance class to XFN links?)
   order activities by importance (twitter.com entries are higher than unknown entries)
   refresh RSS feeds every so often
   look for changes in XFN friends list
   apply filter to aggregate RSS feed and generate high-value activity stream

 output: RSS feed of high-value stream
