This doesn't work for web startups, but for people selling real products I think the best thing to do is apply the baggie test. That is, when Richard Garriott made his first computer game he put the diskettes in clear plastic baggies and gave them to the local computer store to sell. Similarly, O'Reilly started his publishing empire by selling stapled xerox copies of a unix FAQ he wrote at a trade show.

The idea being that if people would buy your product if they saw it in a baggie, you probably have a good product/market.
