In its July report American Customer Satisfaction Index  says:
"Social Media: Wikipedia (+1% to 78) takes the top spot, while YouTube
(+1% to 74) comes in a distant second. Myspace drops from this year’s
Index because there were not enough users to create a statistically
significant sample. Overall, social media is one of the lowest-scoring
industries measured by the ACSI—only airlines, newspapers, and
subscription television services score lower." 
So, not bad at all.
