Gearing up to be a "Grup"

Check out this great article on a newly-defined demographic: the "Grups." I'm impressed with the article for three reasons:
1) Provides a catchy name we marketers can toss around in brainstorms to define a powerful demographic.
2) Nails it. This article is smart and quickly outlines sample characteristics of these marturing Gen Xers.
3) This highlight of the "grups" is evidence that the lines between Gen X and Gen Y are blurring fast, making the groups' cultures and interests (read: what they swipe their cards for) even more lucrative and important to understand.
