how to turn compost

https://www.youtube.com/watch?v=Ki3O4KvdX08 Cali Kim shows us how she turns her compost pile- either with an aerator or using a pitchfork. She has me curious about these Smart Pot Compost Saks- It's a "geo-textile fabric" sack that can hold up to 12 cubic feet of material. I can see the appeal in that it's easier to move around than a compost bin and has better aeration than a trash can composter would. Hmm maybe I'll try one of these for the spring time...
