Pigment has 3.4 stars in the Amazon Appstore (129 reviews thanks to Amazon's FAotD), and 4.8 in Google Play over only 8 reviews, but somehow I don't think I'll be taking them up on their offer.  What a depressing email.


N.B. The conversion table looks like this:

Dollars	Play 5-star reviews	iOS 5-star reviews	Youtube views	Facebook Likes	Google+ Likes
$4	3	2	666	400	40

So, a G+ Like is 10 times more valuable than a Facebook Like?  I'm guessing that's less about how effective they are for marketing and more about it being harder to spoof Google than Facebook.
