The tragedy in Japan and the use of Web 2.0 technologies to spread the word about the disaster has increased awareness about Tsunamis, Japan’s spirit and Nuclear power as well. Microsoft tried to leverage their twitter presence to pitch in but were caught off guard by the backlash. My colleague called the tweet "insensitive". Microsoft later made the right move and tried to fix the damage by talking about their various efforts.
Now the Bing Maps team has come up with an interactive map showing the before/after images of the disaster. The Bing Maps application is pretty simple to use and if I may point out, Microsoft has placed a link on how we can help the relief efforts in Japan.
