You know something tsl? Road bikes
are fun to commute on. (on which to commute?

) I think that most people are best served using bikes which are able to mount larger tires and fenders, as well as having braze-ons to carry loads without wearing a (yuck) back pack, but I can't deny that the nimble spirit of road bikes is a blast going down the road.
So, meh....road bikes are cool.
That said I commute on a Surly LHT. I still ride a 1985 ischiwata-tubed road bike for fun sometimes.
