GoPro owners, how do you mount yours?
What works? What doesn't?

Chest mount is the best I've used. Gives a better impression of speed.
Seatpost facing backwards is good if you are riding in a bunch, gives good chase footage.

Chest mount, but the key to an interesting video is to vary your shots, including lots off the bike filming bikes going by.
