Honestly, I think it would benefit the site if the role of every board were more clearly defined. While it's obvious for /new/ and /meta/, for /gm/, /nice/, and /r9k/ it's a little different. We first have to ask ourselves, what's the point of /nice/? It was created in response to a certain somebody flooding /r9k/ with shitposts. Which brings us to /r9k/, if it's just a 0-effort shitposting board then why isn't it just a /b/-equivalent? What's the point of the robot if it's hindering the board's purpose as an unmoderated dumping ground for garbage? Why not rename it and repurpose it? It will probably cause less friction between posters if everybody goes in expecting it to be a shitty board, and it'll encourage more posts, as people will be more willing to post pointless threads, and they'll easily be able to give no-effort replies without the robotwhich has always been a gay as shit, failed-experiment. It will also justify the existence of /nice/. As far as /gm/ goes, if we are to consider the other two boards as being 'off-topic', then you have to wonder what the aim of it's existence is. General media is a broad topic, and since most people probably spend their day CONSOOMING media, perhaps it's just taking away posts from the other boards. I personally don't think the topic is niche enough to explicitly encourage discussion that wouldn't happen elsewhere.
