Social media is the new TV. TV can be educational and it can be a waste of time. It really comes down to a matter of use.
On the flipside, social media makes us all content producers. We make more when we can share it and get feedback. If you create content, social media is a gateway for showing your work.
It’s the mindless consumption of selfies, cat GIFS, and digital voyeurism that are a waste of time.
