That's what it started out as, for sure. However, is it really "staying in touch" these days or is it simply reacting to and maybe adding a response to whatever status or content was placed in your feed.

Don't get me wrong, I'm not some anti-Facebook snob looking down on everyone else. But I have greatly reduced my use of the platform and only really use it for some groups I'm part of. While I do interact with family and friends, saying I use Facebook to "stay in touch" these days is a bit of a reach in most cases.
