Fred Wilson looks at evolving vs. designing a business.
For years, I have been fascinated by the fact that many of the very best startup companies come out of "side projects". They are accidents really. eBay, Google, and Yahoo! are all examples of this mode of starting companies. Delicious was born this way. One of my favorite web services, Sitemeter, started this way. So did Vimeo. I could go on and on, but like a Oscar speech, I need to stop. Sorry to all the "side project" startups I left off this list.
