What's neat about it is that he can spend time on A/B testing and stuff like that. Also, it's the sort of app where you have a problem, you google it, and you buy it. These are great products to sell. With apps like mine, users need to warm up to the app for much longer.

With me, I spend all my time working on new products or supporting the existing ones, so I always feel sleazy neglecting that in order to tweak marketing.
