I maintain a couple of projects on GitHub (when I get the chance to).
The main two (at the time of writing) are:
An API for simplifying authentication and querying of SharePoint sites, for iOS written in Objective C.
A Twitter-like social network site I built myself in Ruby on Rails to teach myself the framework, as well as to teach myself Twitter Bootstrap and use of Redis from within a web application. This is up on GitHub so I could play with Capistrano.
Feel free to fork either if you really want to. For any questions or support requests, use the GitHub site to raise queries.
