We're on Github! Join in.
The interest group now has a Github organization: https://github.com/LibraryCodeYearIG/
If you have a Github username, share it here so you can be added.
We can use this for the projects we talked about at Midwinter once we select those, but in the meantime don't be shy -- if there's something you'd like to share & hack with your fellow librarians, this is your space.
