I think that I don't have a different personality online; some people do though. They act different like they will be meaner because they are braver when they don't have to say it to your face which is actually not brave at all. A lot of people just try to be funny and it ends up hurting somebody, which is called cyber bullying. I'm not about to talk about cyber bulling and all of its effects because everybody knows about it and it would just be plain boring. So don't worry.
I don't have a different personality online, I think that if somebody saw my blog and it didn't have my name on it then they would know that its mine. I talk about some of the same stuff that I do in my real life and I incorporated it into my blog. When I saw my friends blogs it was so truthful and like them that I read it the way that they would say it. Which was pretty funny because the people I hang out with are funny... at least to me. You can tell a lot about a person by the colors that they use, what they write about, how much they write, and if they make list a lot.
