Monday morning questions

It's still Monday morning for the next 8 minutes, and here are some things I'm wondering about:

1. Why is the rest of the corporation not using the My Site feature at our SharePoint intranet?
2. What can I possibly write about regarding SharePoint that somebody else can't write better?
3. What is claims-based authentication in SharePoint?
4. Should I be concerned that my 19 year old son on break from college has taken up World of Warcraft again?
