These are the three things you need to know about this week's show:

1. We aren't missing anything in a world without Walter Cronkite. At least that's what media theorist Clay Shirky thinks.

2. Kids stopped using abbreviations in texting and emailing when their parents started. Linguist David Crystal says that the age of the smartphone isn't changing us as much as we think.

3. Forget sitting down to a meal. Soy shakes may be your future - which concerns Ruth Reichl.
