Gritter is an example application built using Goji, where people who have nothing better to do can post short 140-character "greets."
A good place to start is with main.go, which contains a well-commented
walkthrough of Goji's features. Gritter uses a couple custom middlewares, which
have been arbitrarily placed in middleware.go. Finally some uninteresting
"database models" live in models.go.
