Every hour the aggregator reads the "feeds" you're subscribed to, as few as a half-dozen, or as many as you like. When you see an item that you want to amplify with your own comments, or pass on to others in your organization or interest group, with a couple of clicks you can "route" it to the home page of your weblog. Aggregators and weblog software are flip-sides of the same idea. Weblogs are for writing, aggregators for reading, and at the intersection is routing.
