Could be true. All depends on the direction they are given. But it doesn't have to be mutually exclusive. Nothing has to stop because they added someone who is suppose to engage with the community as the main part of their actual job responsibilities.The thing is: our current system works because people are free to share what they are working on. When you get an intern in charge of a community, they frequently aren't free to share anything, and have nothing to do.
Perhaps this is a false dichotomy, but I feel like we stay with the current system and get great tidbits less often than our ravenous appetites would like.....or we get an intern, and get frequent posts with far less 'content' than we would really want.
Might be a bad example as it's AAA, but a community manager kept the hype train going nonstop from the launch of Total War Warhammer all the way to the launch of Total War Warhammer 2. And they sold a lot of DLC.
