I'd never heard of this law before I saw the link on Haddock.org. The basic statement is Good customers make for good products. When the customer can't distinguish a good, but more expensive product, from a poor but cheaper one the cheaper, but poor quality, products come to dominate the market. A marketplace with more experienced customers with a better understanding of what they want will support better products. I wonder how this applies to the product I work on. We've certainly faced the problem of trying to sell something for which there wasn't a well defined marketplace, perhaps we're going to next have to fight off a bunch of poor quality rebrandings of software originally written for other domains. Anyway, here's Moen's Law of Bicycles.
