Let me tell you about a few good podcasts. Then, if you're so inclined, suggest one of your favorites in the comments section below.
"¢ This Week in The Economist. Go back and listen to last week's episode, if only to hear a distinguished British gentleman discussing Anna Nicole's "celebrated, American breasts, engineered by silicon to be as broad and bountiful as the prairie."
"¢ Grammar Girl. Because we as a society don't talk enough about punctuation. A recent episode was all about semicolons; I'm almost afraid to use one here.
Fire off your suggestions.
