As the guy modding the first mafia game..
1. I agree with the sentiment that Mafia shouldn't be in the default RSS feed. I like logging off of isotropic, seeing something in the RSS feed about a card I just played with, and clicking a link. Mafia removes that joy, and it doesn't really help anyone, the mafia threads will always be super active, you don't need an RSS to know that.
2. I haven't read this whole thread, but Ozle crossed the line a bit by saying "I'm not cracking jokes in my mafia game because I don't want to look suspicious". If he made a comment strictly about site administration that'd be fine, but I deem that as game related. It violates the principle of providing everyone equal access to game related information by keeping it in the proper thread. I'm probably going to post a link to this thread in mafia I to "annex" it.
3. If the spectators want to discuss, I can just make them a quicktopic. A quicktopic is an offsite forum thread that anyone can use, but only if they have the link. I'll share the link with anyone who pms a request for it.
