Spending time on social networking sites can lead to jealousy toward romantic partners, a new study indicates.

The results are based on a survey of more than 300 college students, and reveal a vicious cycle that plays out in the digital ecosystem called Facebook and ends in a frenzy of jealousy feeding jealousy.

Facebook, which announced its 200 millionth member this year, lets users set up profile pages on which "friends" post comments, photos and other banter, for the most part.

Student spends time on Facebook. He or she monitors the profile page of a significant other, finding ambiguous information about their partner that they otherwise may not have access to.
