I've heard that they have people who go around the internet and read fan comments so they get feedback. However that doesnt mean they want fans raging and being... well typical internet posters on their boards. The moment they announce something controversial there's always a meltdown from all the angry fans. 10 days later everyone has dealt with it, or has mellowed to like it. DC might not want to deal with it. Or maybe its a very costly thing to run. I dunno.
