Things I've worked on...
Most of my OSM activity has been in Jalalabad, where I've trained a small team of Afghans to edit OSM. They're currently mapping out Jalalabad, and the surrounding areas of Nangarhar. http://www.openstreetmap.org/?lat=34.4302&lon=70.4601&zoom=12&layers=M
I also coordinated the license change to make the existing AIMS road data set license compatible with OpenStreetMap. Many thanks to Wonderchook for handling the bulk import.
I went with HOT to Haiti. Pictures from Haiti
