I'm in constant communication with all of my friends, despite sometimes not seeing some of them for weeks at a time. I'm in contact with old friends and family members that live so far away I would realistically never see or talk to them. I'm constantly in a discussion or collaborating on a project with my fellow filmmakers or keeping up on what my extended family is up to.
There are a lot of reasons social media is awesome. It can go too far, and it's all about how you use it, but saying that it has no point just because there's a lot of garbage on it is throwing the baby out with the bathwater. Sometimes I become obsessive and spend too much time on Facebook, but as a tool it's invaluable.
Let me ask you a question. Why,can't you just use a phone for all of that?
Phones? These newfangled thingamabobs!
Let me ask you a question. Why can't you just write letters for all of that? And if it's really urgent, send a telegram!
why do you assume I don't. :)
