That is bad. Meta and Reputation are the boards where most of the forum politics, bitching takes place. I'm surprised you called them good sections because it dissolves the entire point of running a bitcoin forum. Most happening topics in those boards revolve around leaving feeback back to each other and how untrustworthy someone is.
Can posts that identify others as scammers not be high quality posts? There's several threads within the reputation thread which have gone into depth, and investigated their claims quite thoroughly. These investigations take time, and effort. Just because there is a lot of bitching that goes on within that section doesn't take away from the fact that there's some genuinely good posts in there.
There's also a few bitching that goes on within the Development & Technical support sections. Although, I'll admit to a much lesser degree. But, I've seen a few posts which attack each other for no real reason other than they disagree with each other. In fact a few members like to push their agenda against achow101 over there for whatever reason.
I also enjoy some of the discussions that come out of Meta, and although there's been a massive up rise in shit posts here recently its not all bad. For example, recently there's been some pretty good suggestions regarding moderation, and how to identify, and deal with the current problems of the forum.
