Being so close (but oh, not quite!) to that demographic, I understand why. My Facebook feed is littered with posts all day long from friends across the country. Some are posting photos of their kids, others are posting photos of last week's huge party — but they are all contributing huge amounts of content. USA Today quotes several women in their piece on the subject, most referring to keeping Facebook open all day while at work and posting lots of content to a wide network of friends. One even admits to refreshing the page up to 60 times per day, which seems slightly excessive.
The research also concluded that about 73 percent of the entire online audience contributes in some way to social media; women contribute at a higher rate than men do. While these results don't surprise me, I am curious to see if this will shift over time. Will a generation that grew up always having Facebook grow tired of social media? Will more people continue to adopt it? Will it always be around?
