I'm not sure how we missed this, considering I've made it a personal campaign to get every project on Github having an explicit license, but somehow we don't have one. I'm thinking CC-BY or CC-BY-NC?
We need to make sure to ask @treyhunner, too, since I've already merged in his commit.
I vote for CC-BY. I don't care what anyone does with our blog content.
@xiongchiamiov consider my extremely minor change to be under whatever open license you're using. Creative Commons (or even anything on http://opensource.org/) seems appropriate.
Add CC-BY license. Fixes #16.
Merge add-license (#17) into gh-pages
