Being interested in Bsn does not equate in being totally interested in DAI
The Bioware Social Network is made of of a variety of topics. People choose topics of interest, things they like, then they discuss those interesting topics.
For example, I don't post in the Mass Effect Andromeda thread because I'm not interested in the game. I could post there negatively, but that would just be trolling. Instead, I post in some of the DAI threads.
Another example, there are a variety of threads dedicated to certain characters. I don't post in any of them unless I'm really interested in the character.
You clearly post in the DAI threads because you're interested in DAI.
The BSN isn't a topic of interest. There is no thread to talk to the BSN or about the BSN in the BSN. The closest thing I've seen to this would be the Drinkquistion thread and that' still not the BSN. That's just a small group of people chatting about what that small group of people are interested in. They don't represent or communicate with the entire BSN.
