The main problem here is that you are assuming that the community will change. That moderation will change. When in reality the community will be staying the exact same. Right now, look at what happens when a thread is accidently posted in Gaming instead of EtcetEra... you get people joking on the first page and making lame gaming references.3. When something Trump-related does get posted in the Entertainment board (NFL anthem protest drama, Lebron vs Trump etc) there will be a bunch of pissy people saying this is our safe space, bring politics back to Etcetera board etc. Basically segregating people and causing unecessary fighting and thread whining.
During the EA Sports Mass Shooting, the thread was first in Gaming, and later moved to EtcetEra. And yet without the Mods posting that the change had happened, you wouldn't have been able to tell the difference in reaction.
If people start complaining about where a thread is located, well doesn't that run afoul of the rules of the forum? Do we not trust the community to report those posts, and do we not trust the Moderation staff to deal with them for Thread Whining? They take that very seriously. Do you seriously think that a type of community will form that is somehow completely against what the common culture of the forum is?
The answer is no, and that's why this whole point is invalid. Simply changing the layout of the board won't change the fundamental construct of the forum as a whole.
