Congratulations to ProPublica’s Sheri Fink, who just won the 2010 Pulitzer Prize for Investigative Reporting for her story about a New Orleans hospital in the immediate aftermath of Hurricane Katrina. (She shared it with Barbara Laker and Wendy Ruderman of the Philadelphia Daily News.)

We wrote about Fink’s terrific piece twice last fall. First, Zach Seward noted the huge cost of producing the story — $400,000 by one estimate — and the unusual cost-sharing between ProPublica, the Kaiser Foundation, The New York Times Magazine, and Fink herself. And I (gently!) tweaked the piece’s online presentation for not being as reader-friendly as it could have been.
