Selling a web product / company

Great blog post here from Evan Williams on the current trend to sell web products. Barry Diller actually said something Tuesday at Web 2.0 that was pretty good. In response to a question from an entrepreneur, apparently about whether he should sell his successful web enterprise, Barry said: "Don't sell. The way you build equity is to hold on." Which got me to thinking about lots of web companies that have had "successful exits" and wondering if maybe they shouldn't have been so hasty. Evan Williams blog post
