That's part of the reason I don't bother with twitter either. I agree that everyone seems to get along better here. Yet another reason to choose to talk on their official forums, since according to them, they had to pick. I get that it can be a lot to manage, but... it's why this place is here 
I got very scathing in a post last week about it. Since I'm much more mellow about it, I can say that constantly being directed towards social media for answers is annoying as hell. Twitter is likely to give you a dismissive, curt or snarky post. It doesn't appear that they read FB comments aside from the barest of moderation. Being told to leave a comment at the end of a blog with little to no response. Having a community manager non-existent while trolls like the one that started with a V running around saying some of the most repugnant things over and over again, to the point where those that supported his some of his points were sick of the monotony in his posts. Being told "we're listening to feedback" without really telling us what they've been listening to. This is a big fan base and if I could capitalize on the different ideas/issues/concerns that the community had, I'd be rich. The end product isn't always clear as to what their intentions were. I would never accuse them of lying, but without even utilizing their community manager, many posters are left up to their own interpretation.
A lot of folks dislike or even hate social media and would rather come to the official forums for official news. Heck, we can't even read patch 7 notes unless we hit up the blog section of the site. I honestly think an active community manager would help with this. You know, make sure the latest patch notes are up on the forums the day a new patch/content release is out. Addressing trolls and concerns in the community, and not have us beg the BioWareMod to get the worst of the bottomfeeders out. Maybe even giving us a peek behind the curtain.
I remember Allan among others would explain more about a dev's point of view or what exactly a specific dev does, which helped clarify things for other posters. I read some posts from David Gaider that went a long way to explaining why the DA team went a certain direction. I didn't always like it, but that's the dice you roll when you ask a question. Sometimes the answer you hear isn't what you're going to want to hear or something you like hearing. So I always appreciated the time that Jessica, Allan, DG, John Elper, Conal Pierce and yes even Chris Priestly (when he wasn't on a power trip) have taken with us over the years.
I need to stress again that I don't think the writers or developers owe us anything, and that the way that some of the forums treat those people is wrong. However, a community manager is supposed to be that middle ground between the devs and the fans.
I don't hate on EA or BioWare, and I'll never entirely understand the crazy levels of vitriol that is flung their way. Even with that said, there are times where I can understand where some of the angriest people are coming from on this. It does bug the crap out of me that the person that is supposed to be communicating with the fans last posted on launch day and hasn't even bothered to come online for almost 3 months.
Is there some sort of policy that states that interaction on the boards is discouraged and even the community manager is recommended to communicate through any accepted method that isn't the forums? I can live with it if that's the case. I won't exactly like it, but I wouldn't rant and rave about it. I'll have a better understanding as what I should expect.
