In its July report American Customer Satisfaction Index [1] 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." [2]

So, not bad at all.
