I absolute love the new Smiley campaign that 37Signals has implemented to track (and publicize) their customer satisfaction. Absolutely genuis!
In a recent article, they also share some insight into the data that they aren't publishing and the analysis makes for some interesting reading. As a 37Signals customer and someone that has tried to build his own business using the best of 37Signals knowledge, I love how I can actually see the team make a massive effort to get to 100% customer satisfaction. That is absolutely immense and I really appreciate how they are going about this in a very public, transparent and honest way, which just installs so much faith into them as a team and a company.
