There isn't a lot of a difference to me: the obvious has been stated by nearly everyone. You're right that there will always be some that can benefit from what one might consider obvious, but the amount of people depends on the level of what you're writing about. There are people that don't know how to change the default slogan on a WP site after all.

But don't get me wrong, I'm not trying to say that nobody should write about that, I'm offering my perspective on why I probably wouldn't.
