Once used mostly for one-time promos and marketing, Twitter is now something businesses are relying on to provide customer service. For instance, Southwest Airlines tweets to alert folks about delays. And Best Buy responds to questions and complaints via Twitter. And they're not alone.

Let's say you're thinking of ordering a pair of shoes online and you want to know the store's exchange policy. You could pick up the phone — but then you'll hear the old recording: "To ensure quality service, your call may be monitored or recorded."

Timothy Courtois' family had been worried about him for weeks. They repeatedly told police in Biddeford, Maine, that the 49-year-old was off his meds for bipolar disorder. And police were also told he had guns. But still, because he wasn't doing anything that rose to the legal definition of imminent threat, police said their hands were tied.

There are new glimmers of hope for the only known U.S. prisoner of war held captive in Afghanistan — 26-year-old Army Sgt. Bowe Bergdahl, who was captured by the Taliban more than three years ago. After lengthy discussions, it appears his captors may be more receptive than ever before to finding a way to send him home.

A couple of thousand years before the Egyptians preserved some of their dead, a much simpler society made the first known mummies.

The Chinchorros, the first mummy makers, lived about 7,000 years ago in South America, on the coast near the border between modern-day Peru and Chile. The desert area where they lived was so dry, dead people turned into mummies naturally.

Bud Selig, the commissioner of baseball, has persuaded his owners and the players to add an extra wild-card team to the playoffs, so now five teams per league will qualify.

Not only is this terrific for the fans, but Selig also wisely managed to make it so that the wild-card teams engage in a one-game showdown for the privilege of being the team that joins the three division winners in the battle for the league championship.

I have just the old-fashioned word for this newfangled development: nifty.

A listener to sports radio station WWL noticed an uncanny resemblance. New Orleans Saints quarterback Drew Brees is the spitting image of the late U.S. President Rutherford B. Hayes. That is, long before the 19th president grew that long grey beard.

A quarter of the state is classified as being under "exceptional drought" — the highest level recorded. As creeks and riverbeds dry up, farmers are drilling deeper wells to get water for their crops. Now the state is cutting back its permits because of environmental concerns.

Republican presidential candidate Mitt Romney was in Miami, where he courted Cuban-American voters Monday. They're one of the few minority communities that vote solidly Republican. In a news conference Monday, Romney suggested voters don't care about a candidate's race.
