Talking about television, sports, politics, having conversations between friends. Twitter is a forum for people to do all of the above. Anyone can do or say anything they want on the social media outlet. Sometimes that allows for annoying, silly tweets about people's mundane activities. But on the other hand, it enables the sharing of ideas, passions and humors. And to the delight of fans, it's not just your average Joes doing all these things on Twitter.
