As the license thermometer[1] turns greener I was interested in how far 
this already effects the map data. So using the planet history I took a 
closer look on the ways.

So far 3700 mappers agreed to the new license. Out of 68 million ways 46% 
are created and edited only by people who did accept the ODBL. 42% were 
not edited by a proponent of ODBL, the remaining 12% of the ways have a 
mixed history. You will find a map of the ways colored according to their 
license (red = CCBYSA, green = ODBL, yellow = partly ODBL) at
