Right now it is a bit of a guessing game for anyone wanting to create a marketable skill. Amazon have not released demographcs of Alexa users, or even the number of Echo units sold. So we're essentially blind to our audience. If Amazon would release basic market information, things like age distribution, gender distribution, and all the fun things Amazon collects about its users, about The Echo then it would help choose appropriate skills to develop. Even if Amazon made this available for purchase, it would put us in a better place than we are.
