Blogging is fun for everyone

So why don't we all do it some more? All day long I read read read at work. Then I come home and read read read some more. I need to write something, even if it is just drivel in pixels. So here I go, shouting into the empty hallway (to switch metaphors inadvisedly).

Could someone (everyone, in fact) explain this sentence to me?

For all have sinned and fall short of the glory of God. (Rom 3:23, NIV)
