Often in the development of a site I come across the need to display the size of a document next to the link targeting it. I also like to display the type of file the link targets, for example, when linking to pdfs, mp3s or Word documents. These indications distinguish the 'attachment' link from a normal web link, whilst also giving the user some inkling of the time they will need to wait to view the resulting content. So I was pretty excited when Simon bounded in from work and enthusiastically demonstrated json-head , a Google App Engine application he built on the train home.
