Facebook's new 'Timeline' profile pages, the latest 'improvement' by founder Mark Zuckerberg, has hurt the site's popularity, according to a survey by the American Customer Satisfaction Index.
According to the study, about 61% of people are happy with Facebook's service, which is less popular than Google Plus, Twitter, Wikipedia and Pinterest.
The American Customer Satisfaction Index said to the Daily Mail: "Facebook’s drop coincides with the release of its Timeline profile, a significant change to the look and organization of its pages. Users complain that they cannot opt out of the new profile design."
"The sheer volume of advertising on these sites is another contributor to low satisfaction. Many users are uneasy about how their personal information is used and often do not see value in the advertising messages that are targeted to them."
Google Plus has grown to 250 million users annually and has 75 million daily visitors, overtaking Twitter.
