Chaos Communication Congress/27C3
From OpenStreetMap Wiki
Also in 2010 OSM had an own stand to promote the project to the hackers .
Notes for next year
- get more than 2 tables, 6 would be good
- get printed maps/posters of Berlin, organize them before Christmas
- organize promotion material (bestofosm.org poster, flyers…)
- tables preferable on B floor with space to hang maps on the wall/windows
