This video is a conversation between Slashdot's Timothy Lord and informal OpenStreetMap spokesman Serge Wroclawski. Serge stresses the point that OpenStreetMap isn't a mapping application, but consists of the data behind mapping applications; that there are many apps that use OpenStreetMap data; and that you are free to use OpenStreetMap as the data engine behind a map-based application. You are also welcome, even encouraged, to contribute, and you may want to check out the OpenStreetMap Foundation, which is "an international not-for-profit organization supporting, but not controlling, the OpenStreetMap Project." Now comes the question: Do you really want Google or MapQuest or another commercial (or government) entity to know where you are and where you're going? With OpenStreetMap you can download maps of your area, country or even the whole world and keep your travels confidential. You can also help create accurate maps of the areas you know best, including points of interest chosen by actual users like you, not because they paid to have their names on a commercially-produced map. A last thought: In addition to watching Serge in the video, you might want to read an article Serge wrote for his blog that The Guardian picked up about the need for OpenStreetMap. The 195+ comments attached to the article are interesting, too.
