You don't even need to write "© 2010 John Doe" on the blogNot true in all jurisdictions.
Assuming you're speaking internationally, I would guess that very little is true across all jurisdictions. But I don't know much about international law.Yes, speaking internationally. Copyright is not granted automatically on creation everywhere in the world. It wasn't granted automatically in the U.S. until relatively recently (when they changed this to be consistent with the UK, iirc), and a lot of places that followed the U.S. and have yet to catch up.
