The Guardian: Lawyers say facebook and Twitter have become a significant threat to marriage – with social media now a factor in an increasing number of divorce cases.

According to research, one in seven married individuals have considered divorce because of their spouse's postings of Facebook or other online sites.

A similar proportion admit that they search online for evidence of their partner's infidelity, while nearly one in five say they have daily rows because of the way their husband or wife uses social media.
