Until exactly what is accomplished? Or rather what would you like to see accomplished? What is the goal?
Now now before the U word is started to be tossed around I'm nit asking looking for trouble. I just have a haunch.
While I did this only a little bit back in the day, I think there's nothing wrong with anyone doing this so long as they are being respectful. At the very least they're keeping our community and CoH in their heads. What does that accomplish? Who knows, but it may one day be enough to get a thought stirring in the right person's head to make something good happen.
I've read a lot of articles about how social media has tipped the scales toward consumers in the past few years. Stories about people getting screwed by a company, taking their fight to twitter and the company immediately responding and righting the situation. When a company makes a page on a social media they're saying "We're here to interact with people." Thing is, as opposed to a commercial we all watch, the interaction goes two ways, giving consumers the power to interact with the company.
No company wants their name trending in a bad way on twitter, and they don't want to think whenever something is put on facebook they'll be reminded of a past wrong. If nothing else, we're making NCsoft SERIOUSLY reconsider closing any future games because of all the problems closing CoH caused and is still causing for them.
I think anyone doing this should be professional and understand what they post will reflect on our community. Outside of that condition I say go ahead, let 'em know we're still here.
