I have around five separate templates that I use, depending on if it is an API portal, and open data project, or a handful of other variations I use to collaborate around API related projects. I wish Github would let me specify my own templates, allowing me to add one or many template repositories, which could be used to spawn my new gh-pages projects. This would save me a couple of extra steps with the setup of each project.
I'm not sure how many projects, others Github users are setting up, or maybe I am just special snowflake, but I can't help but think others would find this beneficial. As another more advanced feature, it would be nice to be able to have a reseller layer to this, where I could create account level template galleries, where my clients could then setup new organizations, and repositories, all driven my a master set of templates that I control.
Just brainstorming the possibilities here. It is what I do. If you happen to stumble across this post Github, it would be a sweet new feature, that I hope others would find valuable too!
