These blogs are random thins people can write things about.

Hell my last blog was about getting food poisoning at the weekend. ^_^'

Blogs are intended to be a sort of on-line dairy, for people to discuss their daily stuff with folks and say what a good/bad day they've had.

In other words, blogs are purely social reasons... On the One Piece wikia, I've seen them have fanfiction, polls, etc. Its something thats just a little bit of fun and helps build the community up. By using them you stop being a stranger to the other editors. They also serve a place for would-be-editors to either practice in confidence or edit when there is nothing else they can edit.
