One of my favorite parts of the TWIT podcast is John C. Dvorak, the crankasaurus who injects a needed dose of realism and "yeah, right" into the proceedings whenever people get a little too utopian about the future of the Internet. He recently went to the Web 2.0 conference in San Francisco, and he chronicles the quest for exit strategies and overall frothiness of the proceedings in his latest Marketwatch column.
