I'm glad this works for this product.<p>However, I'd argue it is generally not applicable. Say you launch a free application (perhaps monetized by a supporting PRO version, in-app purchases, or ads) that gets a few thousand downloads per day. As a CEO, you can't spend your precious time replying to those (99% trivial) questions.<p>You may do it for a few months, or a percentage of the user questions, to gain insight into your customers. But, as a rule, I'd rather outsource it.
I really like the idea of pretending that all customers are Mick Jagger and think that it is fantastic, although I now have an image of a pregnant Mick Jagger in my head and I don't like that at all. It is all bulbous and wrinkly, like some grotesque anime demon. I may not sleep well tonight.
