Those who drink the Web 2.0 Kool-aid live in a idealistic world where we can mentally connect a great idea to a great implementation of that idea. We live on faith that the great implementation will come, since there are plenty of smart people out there who will eventually figure out how to make value out of technology building blocks. Sometimes our faith is tested when the killer-app does not show up for a long time. But evidence can restore our faith.
