Simplifeed is a beautiful, private social network for close friends and family. It has been completely rewritten from the ground up using Node.js, the Geddy.js framework. The schema has also been redesigned to use a relational database (PostgreSQL) to make for cleaner models and relationships. Note this is still a work in progress and more features will be coming in the future.
Easiest way is to use nvm: https://github.com/creationix/nvm
