My strong disagreement with you here is a good illustration of the practical differences between Bayesians and Frequentists. As a Bayesian, I'm horrified by the idea of doing anything other than building a segment model and letting the fatness of the posterior handle the low sample sizes. But yeah, that is a pretty good way for a marketer to avoid being too stupid. And I can't say I haven't done this a bunch of times, particularly when doing quick exploratory calculations.
