Would it be such a bad idea to integrate a minimum word count in the discussion heavy boards?
For example, in Gameplay, we would set it to a 100 word count soft minimum. If the post is somewhere between 50 to 100 words, it would go to mods for review, and if it's something actually worth while, but didn't need the full 100 words, the mods could approve it. If it's something just like useless rage, they can deny it, and a notification would be sent to the user.
If the post ends up to be under 50 words, the system won't even let the user post it until they exceed the minimum. This would keep all of those threads with nothing but "title" in them and such from bogging down the system.
And, this would only be implemented in the boards that normally should have well thought out discussions, like Gameplay, SA&S, and even here on Discuss the Boards. Boards like M&G and C&C won't have this since a majority of their posts are meant to have minimal text.
