On a related note, whuffie is not a new invention. There is no difference whatsoever between whuffie and money. They are perfectly synonymous. I get the feeling the author, and many of his readers, seem to believe that he has created something distinct from money (from the Wikipedia: 'Whuffie has replaced money...'). Whuffie, as a currency, is no more different from the dollar than the króna is from the euro.

As a descriptor of currency in an inconsequential economy it is somewhat useful. I happen to prefer the word "karma."
