I heard that if you pinch a bud off every so often ; that bud remains will infact produce more buds. I heard two branches start to stem from where the bud once was. I wouldn't suggest this for the top or anything, but a few at the bottom ; maybe 2 or 3. It won't kill the plant, from what I heard it will just make it stronger. Urban legend? It's gettin' pretty thick out there!
