Nov. 14 2012 is GIS Day. It is a day when thousands of people around the world will demonstrate mapping applications. Although osm is not strictly a gis application, it is becoming more popular with gis professionals. It would be a great day to promote osm either by hosting an event like a mapping party or by coordinating with other events to give demonstrations. It is a great time to show the world all the possibilities of crowd sorce mapping. The site lists events already being held that may be possible to join with. Maybe we could turn it into international mapping party day, where there are mapping parties in many areas across the world. For more details, see gisday.com.
