A growing number of Australians expressed their dissatisfaction with Facebook because of the popular social networking site's culture of narcissism and self-absorption.

A report by Ipsos Mackay released on Wednesday said some Aussies are contemplating on closing their FB accounts but are having second thoughts because the site, which counts more than 500 million members worldwide, helps them keep in touch with friends.

But most of them observed the excessive flow of status updates on Facebook that uses too much of their time and energy in reading.

"Participants also tell that much of what others posted on Facebook was either trivial or obsessively repetitive . . . and that the boundaries between what is public and what is private have blurred," The Age quoted Ipsos Australia Executive Director Rebecca Huntley.

However, some consumers expressed satisfaction that social media sites such as FB place pressure on brands and companies to address consumer complaints, while small entrepreneurs take advantage of the site's wide global reach to build their businesses.

Other survey participants warned of the blurring of boundaries between private and public lives caused by FB users' status update and the data these updates provide to current and potential employers.

Other non-tech findings of the Ipsos survey include a general trend toward pessimism about the future among Australians over job security and critical comments of the Gillard government while being unsure if Coalition leader Tony Abbott is a viable alternative to the current party in power.
