Reading someone’s life updates and watching their videos is not keeping up a connection though. It’s a parasocial relationship that makes us feel like there is a connection whereas an actual connection would require interaction between people. As you rightly noted, one of the main outcomes of the parasocial relationship is that it replaces real life interactions - you no longer have to ask people questions about their lives or figure out how to make conversation when you do see them; you can just reference their social media posts.
