Google is finally giving developers a way to respond to app reviews in the Play Store. This is a great addition since it gives developers a way to defend their apps against unfair reviews, and for improving customer/dev interaction and communication. Developers with a Top Developer Badge have access to this feature now, but other devs are going to have to wait a bit before it becomes available to them.
We love seeing Google add more features like this that help out Android developers. Keeping devs happy keeps them making apps, and we all know that a healthy software ecosystem is the key to the success of a platform.
