200 is generally a mess. I tune to it mostly because once in awhile there will be a fun conversation taking place, and it also I can say hi to people without having to look and see if they are on the roster, then tune to.
The only real solutions to 200 that I can see is either having more mods and stricter rules, or removing it all together, the way the "all" channel went.
More mods and stricter rules I would think would give HTC more problems. Fine line between ribbing someone, who knows it is friendly banter, and someone who doesn't know and takes offense. With more mods, maybe more potential for some players being singled out for whatever reason.
On the other hand, removing 200 for eveyone would have the same affect on the individual as not tuning.....almost. It doesn't mean attacks wouldn't happen, it just means you wouldn't see them. So someone could call you a ho dweeb, cherry picking, skilless dolt, that just got completely pwned. Now, if don't see and and don't care what someone may be saying about you to the community, or "explaining" how a fight went down, then tuning off 200 might be an option. However, then you lose the ability to chat with friends who may be in a different country or channel.
So of the 2 chat options, (tune 200 or not), cross country chat would be the best suited option if someone wanted to travel down that road, as it does not give a soapbox for people to stand on and be a moron...at least not to the entire population tuning to 200. Though there is still country channel, I think many have less tolerance for that type of talk, and is useless to those trying to get a reply outta someone.
