A bit after the fact, but still very interesting information. How Openstreetmap has been used to help NGO’s work in Haiti after the earthquake. A specific webpage has been set up for the occasion: http://www.openstreetmap.org.ph/
A thorough article by Camille Gévaudan, in ecrans.fr (in French).

Un article fort complet d’ Yves Jacolin sur les logiciels et données libres pour la géomatique. On y apprend entre autres qu’ Openstreetmap adopterait une nouvelle licence (en remplacement de la licence Creative Commons actuelle) pour préciser davantage ce que signifie la réutilisation de données et les travaux dérivés.
(Merci P !)

«It’d be interesting for generated printouts of OSM data to encode enough source information to reconnect the scanned, scribbled-on result back with its point of origin, and use it as an online base map just like GPS traces and Yahoo aerial imagery.»

All streets: all of the streets in the lower 48 United States: an image of 26 million individual road segments. The last work of Ben Fry.
«The data in this piece comes from the U.S. Census Bureau’s TIGER/Line data files. The data is first parsed and filtered (to remove non-street features) using Perl. Next, using Processing, the latitude and longitude coordinates are transformed using an Albers equal-area conic projection (which gives it that curvy surface-of-the-Earth look that we’re used to), and then plotted to an enormous image that’s saved to the disk. »
