As part of the ‘hate Google’ machine, OpenStreetMap has gained a ton of popularity in contrast to Google Maps over the past few months aside from being in existence for years prior. It’s a fantastic service and I think it’s great OpenStreetMap is getting the exposure it deserves.
Stamen is offering some alternative tiles for use with OpenStreetMap and they look to be well put together and really comprehensive. If you’re building an app that uses maps, make sure to bookmark this.
