We asked consumers which of 29 descriptors best fit the social media/networking sites they use.  Then using correspondence analysis, we mapped the results among a representative sample of 18-34 year old males/females to gauge relevance.  Pinterest and YouTube delight and are more likely to be for “someone like me” whereas Facebook nets a lot of negative associations (including dated).  LinkedIn is also perceived as dated along with being relatively boring and complex, despite being professional.
