If you've been trying to get your head around this whole idea of Web 2.0, the state of the Web, this whole participatory community social bookmarking and tagging sharing thing, watch this video on YouTube . Then watch it again. It says more in 4 minutes about the evolution of and import of Web 2.0 than I ever could in a gazillion posts. And that's kind of the point. Thanks to an old friend for sharing. Because that's kind of the point, too.
