Cathe addressed this very question in one of her afternoon Q&A sessions on this board. Unfortunately, I can't remember when it was. It wasn't long ago. I will try to find it.
ETA: Here is Cathe's response from December 2012. I don't know how to link to that particular message so I just cut and paste. I've also included the original question.
Hi Elizabeth!
Great question and the answer is if you get DOMS you KNOW you had a good workout. The evidence is obvious.
But if you don't get DOMS this does not mean you didn't get a good workout? Well, it could mean that if you didn't challenge yourself to a level that you are capable of (and you know when that's the case. We have all had those kinds of workout days). But if you did a TOTALLY PUSH YOURSELF WORKOUT and you didn't get DOMS, sometimes its just that your body has acclimated to a specific workout or exercise order or weight selection. You still felt the intensity as you exercised, got a great sweat, felt very challenged, and a good burn in the muscle while doing the workout, but the DOMS just didn't follow. Its totally ok, especially if its a cardio based or enduranced based workout (since the body acclimates to those workouts faster). But this could be a sign that you are ready to change things up so that your fitness gains stay on their game. So if you have no DOMS on a regular basis, try changing things totally around and experience the DOMS difference
so the DOMS isn't knocking on the door anymore

I do tons and tons of reading online and in magazines regarding fitness, and amongst the more "hardcore" lifting crowd - fitness models and the like, there is this idea that if you do not get DOMS you are not getting a good workout.
I get that DOMS means you got a good workout, but if you don't get it, are you not making gains on your fitness and muscle-building?
Thanks,
