Banning all meta discussion on LW of any kind seems like an increasingly good idea—in terms of it being healthy for the community, or rather, meta of any kind being unhealthy.
It is a good idea, provided you also give people an explicit outlet to blow off steam, like http://www.reddit.com/r/LessWrong. Seems to have worked for the basilisk discussions. Alternatively, a periodic “Rules and Regulations” meta thread could help keep meta discussions away from other threads. Anyway, something like this works great for a few of subject-specific IRC channels I frequent or moderate.
