My take on the "word count issue": I think it's more with people having a wall-of-text disease by feeling compelled to provide a thorough examination of the entire structure and conception of their argumentation and trying to already dump out answers to every possible argument that can be raised against it. I'm 100% guilty and I'm trying to change :D .
Now, what I suggest about it is to not try and just make people chop off their argument, but to make them restructure their post by only explaining the point and the basic framework of thought as argument, then placing the big long analysis in a spoiler or in a different section. So only people who disagree with the original points will (maybe) read them or who are interested on how, but it's also helpful for those who are just want to see the ideas already made :D
Yes. I think this is the best solution the group has put forward.
