LW has seemed uncertain about which role it is playing for as long as I've been here.

Yes, that's certainly the single largest problem. If the LW moderators decided on their goals for the site, and committed to a plan for achieving those goals, the meta-tedium would be significantly reduced. The way it's currently being done, there's too much risk of overlap between run of the mill moderation squabbles and the pernicious Eliezer Yudkowsky cult/anticult squabbles.
