I personally have quite a few online names, I swap between them every time I get to a drastically new or more strange area of the internet. The whole beauty of the internet was the fact that it is/was entirely based around text and usernames. Nobody was tracking you and trying to attach things to your real life, nobody knew who you were, and nobody cared. Now we have facebook, people worried about criminals more than privacy, and such. The internet is coming closer and closer to a hyped up phone call medium than actually being the internet. When I want to speak to family, to friends, and with people in my life, I will go and speak to them either on the phone or in person. I do not plan, nor do I understand the desire to have things like facebook where you talk to such a large audiance that you know personally. We get scared when talking to a crowd for damned good reason. Facebook hides that.
I have facebook, but I don't "use" facebook. I never post statuses but I do get the appeal. My 9th grade class had a facebook group were we wrote things and asked about homework etc. And my maths class has a facebook group were we can ask about homework and get help from each other and/or the teacher. Our school uses something iIcan only describe as a social media platform specifically for schools. For me the internet is divided into "internet" and "extension of real life" on the "internet" I'm swedishbadgergirl, except when I do things I deem embarrassing. Like have a tumblr or a fictionpress account and on the "real life" accounts I use my real name. Never shall the two mix.
