Bloggers v. Writers v. Journalists

I have been following with interest the recent debates about bloggers v. writers v. journalists.

I know that they are not the same, but is one really better than the other? Aren’t they just different?

and later…….
Why do you read blogs? (you are here aren’t you!)
Why do some journos and writers hate bloggers?
I am fairly sure bloggers will not replace journos.
But I know a lot of journo’s are now bloggers.
Are bloggers just narcissists, like my sister once told me?
Am I talking crap? AGAIN?

Would adore your thoughts on this.
