1. Children not allowed to talk to people on their block.
2. Online equivalents simply aren't as much fun. You can't hand someone a copy and say “That'll be five cents, please.”

4. Kid newsrooms devastated by layoffs and early retirements.
5. Sports editor kept missing deadline because of yoga classes.
