Should a furnace fan run continuously?

Theoretically, is it more/less cost effective for me to run the furnace blower continuously (24 hrs/day) throughout the winter? I feel that doing so provides more balanced comfort throughout the house but don't know if it will result in less gas usage. Monitoring gas bills will take a number of years with a number of factors like shifting weather patterns (timing, temperatures etc.) to take into account. I also have a cascade humidifier and I'm positive that the continuous blower operation keeps the humidity levels higher (30-40). Calgary has a very dry climate in the winter. I also am guessing that the heat exchanger is not subject to as much rapid expansion/contraction which may result in longer life. Is that likely? Thank you for your comments.
