An amazing map/wiki: Mash-up Google maps and a wiki and you have Scipionus.com, an incredible effort that is allowing people to explain block-by-block what they’ve seen in the Katrina-affected areas.
(via: Steven Levitt, author of Freakonomics, who observes: “Surfing around (the map), the devastation doesn’t seem as bad on the wiki as it does on TV. Houses a block or two from Lake Pontchartrain with no flooding, for instance. This shouldn’t be surprising. TV is only showing us the worst. The people in good enough shape to be entering info on the website are probably heavily selected towards those who fared well. The truth is probably somewhere in between.”)
