First Blog

Im kind of new to this whole Blog thing. I mean, i have tumblr, but I'm not sure that counts...i don't even use it anyways...so what does one blog about when its his first time? how about the fact that the only reason i have this blog is because my teacher made the class so it? I mean, I'm all for it, I'm not complaining, i just don't know what were supposed to do with it :/
