I appreciate the response. I'll try and address each thing you mentioned.
--------------------
but let me tell you what i see. 'Amazon is building their market on the backs of apps by giving them away for free.'
--------------------
This company's app uses a simple software model. You pay $1.99 and you get their app. Your comment decries the entire Amazon model as benefiting them and not the developer.
I don't agree with this and here is why... let's say this company had a subscription-based app or some in-app-payment-enabled app. Suddenly it is on 101k new devices and let's say that 5k of them (5%) buy some simple subscription or even less, some 1-time-in-app-micro-resource inside the app for $.99.
Now suddenly this blog post has a very positive tone to it and the developers are praising Amazon for such a progressive app sales model and we are all here nodding our heads about how awesome it is and you and I are high-fiving each other over Skype Video because we are so excited.
The Amazon model isn't broken and it's not building a market on the backs of its developers. It can be an aggressive, mutually-beneficial relationship if both parties are prepared to take advantage of what Amazon has to offer. These guys weren't ready for that yet, but I am willing to bet dollars to donuts that come this time next year they will have a new app back in Amazon App Store, ready to do the 1-day-free-giveaway AGAIN, but this time they are going to be prepared to take advantage of all the traffic.
----------------------
Its also unnecessarily diminutive to say '... I have to point out that the sales BEFORE the free-app-of-the-day listing[1] were not impressive...". The fact of the matter is they made infinitely more money before the deal of the day then we can say they did AS A DIRECT RESULT of the deal of the day listing.

I agree that my comment came off way too demeaning and I didn't mean it that way. I was getting carried away with making my point that from a sheer-number-of-device-installation perspective, they went from a trickle of water to a firehose in one day and that isn't a bad thing.
