What would you define as a "real relationship"? Is texting someone once a month any different than commenting on things going on in their lives, or messaging them on [insert platform]? My view is no - a relationship, whether by social media, text messages, or shared experiences, does not make any other form invalid or less real. I have seen people fall in love purely from online interactions while playing games, or chatting in IRC - these relationships are as real as any other. One person's notion of relationships may be different than another's, and that's ok, but trying to say one's notion is more real than another is hogwash. Depth is not so easily measured here either - direct text messages can also be just as banal (or more) as social media interaction in developing relationships.

I still remember times before Facebook came to dominate social media. It was difficult to keep tabs on friends, and the barrier was higher to keeping in touch with someone you met casually in person, as there are a lot of people who are less willing to share phone numbers with people they just met - there is something intensely personal about phone numbers or similar to many people, which still holds today. I think many people under appreciate this, and the controls for managing the communication relationship social media gives you (or at least Facebook - Twitter's are garbage).

I use social media casually today - just Facebook and rarely Instagram, and post maybe once a day or every other day. I am in some FB group chats, all which could be text messages, but text messages aren't as robust of a medium (for example, location sharing in a group or easy searching of pictures people want to use to respond with).
