I agree. I totally understand ojbyrne's scepticism, but after a number of conversations in the last couple months I don't have any trouble believing TechCrunch's claim. The question is whether the money is sustainable.
Does it matter if the money is sustainable? I only ask because there is a good chance that the cost to develop the app is much less than 500k. I would take a month of that kind of revenue and parlay it into capital for another venture if it stopped suddenly.
Yeah, I absolutely agree. That's the attitude I see in developers. The apps that make money are often not very complex, so it's worth the effort even if the party doesn't last forever.
