Why this is dangerous is that the community at large is sometimes very incapable of critical thinking, and instead just compress, compress and compress until Blizzard is digging itself into an imaginary hole, and all that is thanks to a COMMENT on a facebook page made by a CM.
As far as I am concerned, Blizzard's efforts with communicating to the fans (the HUNDREDS of Bashiok posts in the past few months only, all the explanations, back-and-forths, developer blog, the patch 1.0.4 and the other goals that are yet to be implemented)
GREATLY trumps one overzealous CM who does not understand that his post, however true it might be for quite a few people, will not only not change their mind, but will only escalate things.
Looking at the big picture, I still have yet to see other examples of teams that are this communicative about their games like Blizzard is - with a few VERY good exceptions like Grinding Gear Games and ArenaNet -, because by large, the industry is as one-sided as it gets. And until Blizzard is the exception to this rule, I do not feel like I should be mad at them for what they are actually doing right.*
I see two ways out of this tunnel.
One is realizing, recognizing and accepting that the developers of Blizzards are not demigods, or not even the peaks of the human existence - they are capable of failing and yes, they say FUCK YOU when someone pokes at them just as much. Especially if they think it is a private facebook conversation, not a public one, but hey. Yes, they swear, they make mistakes, but their goal is to improve the product they are making. And that is more important to me, personally. Might not be for others.
The other way is to close off all non-professional communication channels to all staff and only allow them to express themselves through the official chnanels. Which would be a sad development, maintaining a social prison because they and their community are both not ready for a natural social engagement yet.
Which way do we go?
