Official Forums on a band's website: C or D?

I've seen a handful of forums that are great, but they're definitely in the minority. Sometimes something useful comes out, like the recent James Murphy posting that was noted on ILM where he addressed complaints about copy protection, etc. Then there's the official efforts that are just short of street team promotion where a few paid promo staff keep trying to spurn interest.

So, anything good? Bands that have a useful forum? Particularly awful ones?
