People who can't stop logging onto Facebook are narcissistic, insecure and suffer from low self-esteem.

Researchers from York University quizzed 100 students between the ages of 18 and 25 on how often they checked out Facebook. The students also took a psychological test that measured their level of narcissism. The York team found that the more a person clicked onto their own Facebook page, the higher they scored for narcissism.

The same test revealed that those who can't get enough of Facebook also suffer from insecurity and low-self esteem, which are traits often tied to narcissism.

The problem here is Facebook is just too damn self-affirming. We're pretty sure that if they finally added a universal "dislike" button, Facebook would cease to be such a cyber-swamp for narcissistic/insecure types.
