Late Sunday, Anderson Cooper and fellow part-time hero / full-time correspondent Sanjay Gupta tweeted that they were going back to Haiti. Almost a month after a major quake destroyed the capital, most news crews and their high profile reporters have long since packed up and left. Haiti is no longer front page news and that makes Cooper's return all the more interesting.

It's no secret that CNN sees a spike in viewing during disasters, so is the network just milking the tragedy for ratings? Is it a genuine plea for a people forgotten by the news cycle? Or is it just good journalism?

If you've been wondering why Anderson Cooper hasn't been on his CNN show this week (I believe Soledad O'Brien has been filling in for him), it's not because he was busy spending the day with Barack Obama for a special episode that airs tonight. It's actually because he had cancer surgery on Monday.

Cooper describes on the Anderson Cooper 360 blog that "a small spot of skin cancer" was removed from under his eye. He says he wasn't even going to mention the surgery, but he still has stitches, and when he returns to the show tonight people would have noticed and he'd have to explain anyway (of course, he's probably still going to explain what's wrong, since I'm sure a lot of people don't read the 360 blog).
