I'm fairly certain that if you look around, You can find Plenty of Bioware posts - in fact, I saw a few just the other Day/Week actively posting in the MP section. Then a few more here and there among the other areas.
More often then not, I find them Weeding/Locking volatile threads - I'm certain that they wade through here and read Lots/Most of what's going on, but more often than not, I see them get attacked or berated by people, with the occasional "Thank you for your work" thrown in between hate posts, or posts that don't pertain to the subject of the thread (I.E. Random Johnny in a Smarmy manner - asks BioMod/Member "Why are the tactics dumbed down?" In a thread devoted to say, There being no Brothel in the game.).
Honestly, I'd be afraid to come here for *Anything* If I was them, because for every thread Thanking Bioware, or telling them they've done a good job, I find 5+ more of "This sucks" "You guys *Must* Acknowledge how terrible this game is."
And it makes me sad, really, really sad. To think, I joined just recently to get all excited for DA:I over the past few months, and now I get to listened to the Vocal minority spout Emotional/Subjective problems about their game experience, and call it Objective fact.
Sure, there are things to criticize about the game - And there are threads for doing so in an Honest, Calm, and Respectful manner.
But BSN is going the way of WoW Trade/General Chat. Or it has been for a while, and I'm just finding out what I've stepped into.
