Please read it, it's not long. In the article, utilons refer to the utility your help brings, and fuzzies to the feelings they generate in you (which indeed you can see as utility for you, but you could also count it separately).

The point of the article is that if you optimize for utilons, fuzzies and status points separately - e.g. by doing one thing for maximum utility, and then another for maximum fuzzies - you'll be more efficient in all of them than if you try to find one thing that maximizes all three at the same time.
