John Robb and Dennis Kennedy are blogging back and forth about John's viewpoint that aggregators are more important than weblog tools.
They are both half right. The really important tool is the one that does both. The fact that they are typically found in different apps right now is just silly. Like a video camera that requires an external monitor with no builtin viewscreen to allow you to "create" and "consume".
Every single killer internet app that I can think of off the top of my head has allowed users to create and consume - except the web. I submit that the only reason that weblogs and aggregators aren't usually found under the same hood is because they are usually web apps. If Blogger had started out on the desktop, it would probably allow for some really cool two-way interactions.
Like Radio.
