Difference between Multi-Social Retailer, Mono-Social Retailer, & Non-Social Retailer

There are many ways to classify a retailer based on the sales channels they use.  There is a "brick and mortor" retailer, the "catalogers", and internet-only "pure play" retailers.  I'd like to take the concept of labeling the retailer based on the sales channels they use, but instead apply a label to the social channels a company uses to communicate and obtain feedback from customers.  A company who engages in a multi-social relationship with their customers uses more than one social networking apparatus.  A company who engages in a mono-social relationship with their customers uses one social networking apparatus.  A company who does not engage in a online relationship with their customers is a non-social retailer.  

An example of a multi-social retailer can be seen at diapers.com, or more information about this concept can be found at the internet retailer.
