In addition to the mixed reaction to Louie's post in the comments section, and your response above, this seems sufficient for me to change how I would include Louie's post. It's popular enough that since it launched a business I will include it as an example of a positive externality of Less Wrong, but it's not an example that will dominate the others. I might contact the business Louie's article inspired directly to ask them what they think of this. I figure this would return information at least as reliable as Louie's estimates, assuming the company in question will be honest.
