Although I'm finding myself quite sceptical about it I've been following the Maffetone approach last winter during the aerobic base building phase of my training.
So I use the HRM to make sure that I'm not going over the point where Maffetone says you start becoming anaerobic which is 180 minus your age. in my case 144 Bpm.

My feelings are that this figure, 180, is deliberately set low, but it does reign you in and my speed at a low heart rate has increased by over a minute per mile. I don't feel the need however to use the HRM to run tempo or interval sessions as I just push as much as I can. There is also a lot of chat on the net about LT zones being a bit out dated as far as the science goes, I'll link to this later when I've got the time.
