Excerpt from this article:
Some of the more interesting findings came from its U.S.-based study. For instance, new American moms post 2.5 times more status updates, 3.5 times more photos and 4.2 times more videos than nonparents, per Facebook’s internal stats. And hey, the updates work: New parents’ posts (those from moms or dads) about their babies get 37 percent more interactions from family members and 47 percent more interactions from friends than their general posts.
“Parenting has become a digitally shared experience… Technology enables parents to share the joys, challenges and questions inherent in raising a child with their family and friends both near and far on a regular basis. Instead of mailing holiday cards or school pictures, they’re sharing their child’s milestones through photos and video online.”
