I do not think that social media is limited the ways in which people communicate. I think it is increasing for a few reasons. Before social media and the ability to call, you had to be face to face to interact with someone. Now, with the addition of technology, you are able to interact with more people than you ever would. You can tak to your grandma while she is a 6-hour plane flight away. Not only are you talking to people you normally would, but you can also talk to people outside of your circle. This enlarges your vocabulary, your social interaction, your understanding of other cultures, and more.
