You start your day, grab a coffee and update Bob. Then you swing by your manager’s office and update him. He’s like, “Oh. Em. Gee.” (He thinks that’s cool).
Now you’ve got to update his boss.
You get back three conversations later and tell Janice what happened. You try to ignore the guy listening over the cubicle wall… but then you update him so he doesn’t spread the wrong story.
Now your coffee’s cold. You start your day.
Or, you could write a blog post inside your team space.
