A related article I'd like to see is how to take the lead in a divided market. My (unlaunched, in progress) startup is in a space where there are a three or four competitors with a large customer base, and a dozen or so others with significant ones. They're almost all offering the same (aged) feature set. But it's not like the service has become commoditized the way basic web hosting has. I feel like we're going to have strong differentiators, and a much easier time getting adoption from the slice of the market not already using one of our competitors. But what's the best way for us to get all the people who have sunk their money and time into a competitor's service (and its learning curve)?
