I'm forced to interact with certain people in my life through certain social media tools, but I lost interest in most if it a long time ago. I've tried to quantify what it is that made it so exciting at first, and the best thing I can think of is that I used to meet new people or engage with people I wanted to get to know better when things were first kicking off.
I never wanted it to become the way I talk to my folks, I wanted to talk to that cute girl in my class or some guy in Russia that happened to like the Smashing Pumpkins too. Maybe I'm not using it right, but it seems more difficult to find new people while wading through ads and political posts from peripheral friends.
