Hugh Pickens writes writes "WebProNews reports that according to a new survey, the more Facebook friends you have, the more likely you are to feel stressed out by the site. "The results threw up a number of paradoxes,” says Dr Kathy Charles, who led the study. “For instance, although there is great pressure to be on Facebook there is also considerable ambivalence amongst users about its benefits." Causes of stress included deleting unwanted contacts, the pressure to be entertaining, and having to use appropriate etiquette for different types of friends. "Like gambling, Facebook keeps users in a neurotic limbo, not knowing whether they should hang on in there just in case they miss out on something good.”"
