An interesting discussion went on in the Community Service forums yesterday concerning the role Blizzard developers play in those very forums. A poster was obviously attempting to troll and start some argument, asking if the Blizzard devs actually do read what people write or pay attention to the community at large. Kisirani, a Blizzard developer, responded that indeed they do.
A few interesting things came from subsequent blue posts that help outline the roles of the developers and community managers. First, it is the job of the community managers (CMs as we call them) to do just what their title says: manage the community. This includes the forums and everything that goes on in there. Kisirani tells us that they regularly collect feedback and suggestions and pass them along to the developers. Kisirani makes it a point to say that they don't have enough time to read everything themselves, and if they were to read everything the game itself would not be developed – and again, this is where the community managers come into play.
