The middle of the market is a paradox because of the inherent contradiction between the ease of reaching the nerds and the geeks and the need to reach the middle. The solution, if there is one, is to enter a market to the enthusiastic cheers of those in search of the new, but to build a product/service that appeals to those in the middle. After the initial wave of enthusiasm, you hunker down and ignore those that first embraced you, obsessing instead on the needs and networks of the middle. It’s a difficult balancing act, but it’s the only one that works.
