I've got a small "scratching my own itch" app with a paid and ad version on the store for 6 months, no marketing at all really other than being in an underserved (and small) niche. Paid version has had about 75 downloads, the ad version has a few thousand. By the article's definition, it's "never been downloaded". However, even at such a low download rate, it's basically paid for the cost of putting it on the store, by the end of the first year and assuming the download rate stays the same it will have made a small return.

While it's not going to replace my day job, it was still worth doing IMO.
