A blog about blogging

I'm thinking about creating another blog.

I realize that there is no central authority who defines these things, so I'm asking--if the blog is written by someone who doesn't exist, about people and places that don't exist, and things that never happened, is it still a blog?

Personally I believe it is--there won't be an defined plot or anything to make it a story, really, so it's not like me posting stories or poems or serializing my novel or anything. And of course there will be those who don't get it--they'll either believe it's real or think I'm trying to fool people into thinking it's real.

Anyway, what do you think? Would it still be appropriate to call something like this a blog?
