I recently began to ground the bearing on my table (well...I recently *securely* attached a ground wire to the bearing) and I've noticed much less noise (leading me to believe much of the "rice krispies" I've experienced had nothing to do with the condition / cleanliness of the vinyl.
I've not seen much discussion about this before, and I'd suspect most tables don't make this a logistically simple task. But it's easy with Teres and Galibier bearings.
If the bearing in your turntable isn't grounded, you are missing a bet. If the bearing isn't grounded, it and the platter can generate a small amount of electricity as it spins past the magnetic field of the cartridge.
