How young is too young...to Blog.

I think if a child is old enough to read and write, they are old enough to blog. Granted, they will probably need some adult assistance/supervision, but I don't think it is outside of a child's capabilities to blog.  Kid's are full of ideas. In fact, they probably have more ideas than adults! Oftentimes a child's mind is an untapped gold mine of creativity. Let's tap in. Blog away kids.
