I...exist in real life. I go to college classes, work a simple starting job with Student Dining Services, come back to my dorm, clean up, then either play MCSG or peruse the forums depending on if I have a laptop available or only my phone.
My online social life consists of the following gaming communities (in descending order in terms of most played): MCGamer, Star Wars Combine, Youtube (I comment a lot as well as upload), and (rarely nowadays) The Wrestling Game.
I have like two not-that-close friends from high school IRL. They probably know that I play Minecraft (and I've made it very public tha I record for Youtube) but neither seems to care. All of my Skype friends, and three professors whom I have on Skype, know I play Minecraft, and specifically MCSG.
