This study examines how social media and information-sharing behavior can influence young adults’ perceptions of changes in tie strength within their own personal networks. By focusing on the extended personal networks (27.56 relationships) of young adults, we show that social media leads them to feel closer to their “friends” whom they think of as exhibiting online behaviors similar to their own. This behavioral homophily mainly stems from frequent reactions between friends, when they like or comment upon each other’s posts. Such homophily is also related to the sharing of political news and entertaining content, which constitute a salient affordance in the “pervasive awareness” of social media and lead users to feel closer to those exhibiting similar content-sharing behavior. This similarity reveals how social media platforms help to shape personal networks over time, particularly by influencing user relationships with weak ties who share similar online behavior.
