Do you ground your bearing?

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.
