Are you serious about "thousands a month"? I don't mean to be hostile, I'm just truly surprised -- if the bar were that low (not that these apps aren't impressive, but most engineers write useful apps from time to time) I would expect the market to be rather packed
Nah, most are hundreds a month - a few golden geese can break the thousand barrier, though. But, regardless, have a few of those sites up, and you're making good side income.
