Thanks for your comment, MasterScrat. These are good points, actually our results are preliminary. As we consider this topic to be helpful for developers, we aim to further analyze the data.

I would be very happy to receive more replies like yours to come up with new ideas and different perspectives on how to look at the data, and to prioritize which questions to answer.

- Are there interesting differences in sentiment mean+variance by app category? For example, are utility app reviews more polarized than games?
