At the end of the day, the most crucial thing that’s changed is that almost all the new voices are intensely personal. If you want to be a well-informed citizen of the world, you have to choose who you’re going to listen to. It isn’t about newspapers vs. the Web, or Facebook vs. Twitter, or feedreaders vs. aggregators. It’s about the voices that you choose to hear. This is your responsibility and you can’t escape it. It’s hard; there’s not the time to read everyone who might say something useful, and nobody likes unsubscribing or unfollowing or unfriending.
