I find studies like this very interesting, always have. This is a great article for those who are into social media.
Motivations differ from general population
Luxury marketers take note, according to a February 2011 Affluence Collaborative survey, wealthy internet users connect with brands on social networks for significantly different reasons than the general population. The social networks they use to do so are different, too.
Among the general population, the main reason cited for connecting with brands on social networks was to receive deals and discounts. This result from the Affluence Collaborative survey backs up earlier research from several sources on why consumers follow brands on social sites.
But according to Affluence Collaborative, this was a much lower priority for the wealthy. Their top reasons for following brands were due to a preexisting affinity for and a desire to be kept informed about the brand. The least-cited reason mentioned by all groups surveyed was to be entertained, suggesting that social media marketers still need to provide fans with value, even if it isn’t directly in the form of a coupon or sale.
These findings coincide with earlier research from ExactTarget, which showed that a huge component of liking a brand on Facebook was due not just to an affinity, but as a means of self-expression for others to see. This promotional desire was more pronounced in Facebook users than Twitter followers or email subscribers. Affluents then, in their “love of the brands” they connect with, are largely acting as brand ambassadors.
