First time as a blogger

So I've never been big on the whole blog idea so I'm a little nerveous to see how it goes this semester. I feel what I will use the blogging for is it show articles or videos that I find to tell others in class. I do have friends who choose to blog and basically tell their life story through blogs but I am not that kind of a person. I find it a little odd when people read personal things about me and that's why I think I will just choose to stick with youtube and the internet.
