"Facebook is supposed to envelope us in the warm embrace of our social network, and scanning friends’ pages is supposed to make us feel loved, supported and important (at least in the lives of those we like). But skimming through photos of friends’ life successes can trigger feelings of envy, misery and loneliness as well, according to researchers from two German universities. The scientists studied 600 people who logged time on the social network and discovered that one in three felt worse after visiting the site—especially if they viewed vacation photos. Facebook frequenters who spent time on the site without posting their own content were also more likely to feel dissatisfied."
