Cool. That link doesn’t work for me though. Maybe the new Google Maps haven’t been fully rolled out to everyone yet, or maybe the link is incorrect somehow? That link takes me to the old Google Maps I think, and there are no annotations or anything. Google Maps’ UI for editing is probably pretty neat and easy to use, but just wanna mention OpenStreetMaps – a free open source Google Maps alternative with crowd-sourced data. Personally I prefer contributing to OpenStreetMap over contributing to Google Maps. http://www.openstreetmap.org http://wiki.openstreetmap.org/wiki/Main_Page
Worth considering, especially since Google has such frequent problems here, especially without a VPN. Here’s the link, this one works, but there isn’t much on here aside from Dojo to demonstrate the functionality: Chengdu Maps
