I was not a commuter until June; everything I did was purely recreational. Then once the days started getting shorter I was finding that I no longer had time to do long rides at night anymore, with a whole hour gone from the evening. Thus I decided to start commuting so I could get in an easy 40 miles on a weekday.
I still recreationally ride, but that's mostly on the weekends now, as my commuting trips on the weekdays have pretty much replaced my evening exercise. However I have absolutely no plans to cease my weekend rides for fun!!
