Would be really interesting to see how much you make off this with your donation model. I wonder how much it would affect income if you used someone other than paypal, or had several donate options.
I'm expecting that it's probably not going to go much above where it is right now (which is still twice as much as I figured it'd bring in); despite quite a few downloads from HN, no one has paid for it. That said, I'm sure I could increase paid conversions with some work, but I honestly don't care enough to do so. I built this so that I could build neat demos on my iPad, and there's no way I'll recoup the cost of 5 or so hours of dev time I spent on this. I'm just glad that it's working well for people.
