All of my "big" projects on GH have more than one repo, usually 2-5 depending on what all work needs to be done. Before GH allowed you to create private repos in orgs for free I had hundreds of repositories and had to name them like projectname-website. Now I create orgs for my biggest projects so all my repos are starting to look more like projectname/website instead.
I'll admit, very small change but helps me keep my Github organized.

Overall Github has gotten only more and more important in my workflow. I find it amazing that this site went from "cool tool" back in my college years to "I literally cannot live without this tool" now.
