Add Draft for New Blog Post: The Big Data Elders, Archeology Hour

Here's the draft (export of our work on editorially + post yaml + reformatting to lines of 80 chars). I was wondering if we should consider supporting multiple authors in the templates. Not that I'm planning to write more incomplete posts for others to complete but it might allow us to give you proper credit (have this show up in your author page and next to the title). 

Someone proposed a way to do this here: http://stackoverflow.com/questions/15189008/how-can-i-have-multiple-authors-for-one-post-in-jekyll
