This is the best you're going to get with the traffic the site gets and I'm fine with it, but I went over to check out the coli since it was mentioned and I noticed a few things.
Less bickering: They actually stay on topic over there, where as here, things always pointlessly devolve into personal attacks, roasts, pic gifs that get posted for reactions rather than substance. Granted its funny and I enjoy seeing it, but it kills threads. Don't honestly have a solution for this, just an observation.
Less subforums. The IC is designed for high traffic, which it simply doesn't have.
(And like bilfiger said, merging everything into the Official NFL/NBA/MLB) in Cheap Seats is stupid and counterproductive.
The only things I'd add on my own (which have already been said) are over modding and freepost threads.
-If a mod gets annoyed or catches feelings, they should put that poster on ignore, not ban/jail them. Encourage others to do the same if they're equally annoyed. That's what the feature is there for.
-Don't delete threads unless they're in direct violation of the 'big' rules. Just lock it, with a reason it was locked.
-I understand having something like SL as a safe haven for intelligent discussion, but things shouldn't be sent there if the TS felt like making it a general audience thread. And then the fact that even SL has the RR under it is even worse.
The last thing is, move the ADHD and Pic threads to Donkey. GnS has no trouble getting views. Make people give the "dead" section that is Donkey a look if they wanna freepost/chit-chat.
