The discussion of portmanteaux brings to mind my pet peeve-workaholic.
If we followed the example of infotainment, we should combine work and the ic from alcohol-ic. To use work-aholic would be the same as if we created "infotertainment".
Now workahiolic is a more colorful and easily recognized word than workic would be. I don't know if you all would prefer to play by the rules/guidelines, or if you feel it's ok to be more relaxed about creating portmanteaux.
