If you live outside the interwebs and twittersphere and blog-o-things, you might not be aware that early bird registration to the State of the Map 2010 has just opened:
http://stateofthemap.org/register-now/register
SotM10 will be the perfect place to learn more about OSM and gather with the rest of the OSM community. If you plan to come to the SotM10, reserve your ticket now!
