Women were also more likely to have expressions related to family relationships and romantic relationships.
One of the key findings of this research is that those men who do have expressions of romantic relationships in their profile had expressions just as strong as the women.
(Haferkamp et al., 2012) Privacy has been the primary topic of many studies of SNS users, and many of these studies have found differences between male and female SNS users, although some studies have found results contradictory to those found in other studies.
In 2015, 73% of online men and 80% of online women used social networking sites.
The gap in gender differences has become less apparent in Linked In.
Finally, the histories of some SNSs themselves have ties with gender.
For example, gay men were one of the earliest groups to join and use the early SNS Friendster.
Further, in many cases those historical reactions resulted in restrictions of girls' use of technology to protect them from predators, molesters, and other criminals threatening their innocence.
Like current fears focused on computer use, particularly SNSs and other communication media, these fears are most intense when the medium enters the home.
Hargittai's groundbreaking 2007 study examining race, gender, and other differences between undergraduate college student users of SNSs found that women were not only more likely to have used SNSes than men but that they were also more likely to have used many different services, including Facebook, My Space, and Friendster; these differences persisted in several models and analyses.
Although she only surveyed students at one institution – the University of Illinois at Chicago – Hargittai selected that institution intentionally as "an ideal location for studies of how different kinds of people use online sites and services." In contrast, data collected by the Pew Internet & American Life Project found that men were more likely to have multiple SNS profiles.
Technologies, including communications technologies, have a long history of shaping and being shaped by the gender of their users.
