Staying in line creates a gap that otherwise would not be there of he filtered up and only serves to slow down traffic behind.

My rule is if there is no bike lane, filter only of I'm turning right. If there is a bike lane after the light, filter to the front if I'm going straight or turning left. If the light is on an incline, I always filter to the front.

As far as where I sit in the lane, I apply the motorcycle rule. If a motorcycle would be in the lane and cars wouldn't make dumb moves to endanger them, I go where they would go. Sometimes this means I block right turns when I'm going straight, so be it. All other vehicles going straight would also block right turns, why should I be expected to make things less safe for myself just because I'm on a bike?
