Given the global expansion, the borderless nature, and the social impact of social media, this paper provides an examination of users’ connection patterns in online social networks, more specifically the users’ cross-country connection patterns. We study three highly different social media platforms, Facebook, Last.fm, and 500px, and approach two main research questions: First, we set out to answer which countries’ social media users are mainly connected with users within their own country; and which countries are characterized by a wide spectrum of cross-country (transnational) user connections. In doing so, we also identify the “attractor” countries, being characterized by alluring a large portion of users from other countries to connect to users in the respective attractor country. Second, we compare the results between the three social media platforms under investigation and analyze and discuss differences in the cross-country connection patterns. Third, we investigate whether countries’ attractor values are correlated with cultural features (according to Hofstede). Our results contribute to understanding the complex social ties between people and how they are reflected in connection behavior on social media.
