Add Draft for New Blog Post: The Story of the Big Data Elders

For italic blocks, I finally settled on keeping 80 char lines and making each one italicized. I would have liked to add a line break after those italic blocks but I couldn't get something working (according to [Gruber](http://daringfireball.net/projects/markdown/syntax#p), a blank line with two or more spaces _should_ do the trick but that didn't with kramdown).
