Mute is a simple web app which shows you all the people on Twitter you have muted, functionality Twitter does not offer itself.
Mute was built in a single day; I set myself a strict deadline to see how well I could use the skills I claim proficiency in, rather than learn new ones. The back end is built in Node.js using the Express framework and uses the Passport library for Twitter authentification. The front end is templated in Jade and uses Twitter Bootstrap. The app is hosted on Heroku. All of these technologies were chosen to reduce development time to a minimum. A longer blog post about Mute is in the works.
