How is JSON useful to Java developers?
“In the ﬁrst version of our API, data was available in XML, with JSON support added largely as an afterthought. XML as a means for delivering developer-friendly data hasn’t aged well. Seeing the growing inclination of developers and API makers alike towards JSON, we’ve decided to eliminate XML support and put the energy spent there into getting our JSON implementation just right.” July 2011http://engineering.tumblr.com/post/7541361718/introducing-tumblrs-new-api
