Example post in markdown

A follow up to #4, quick example of how drafting posts in Markdown can make things a lot more :sparkles:.

Converted one of today's post over to Markdown as an illustration. As you can see [by the whitespace-ignored diff](https://github.com/benbalter/api-evangelist/commit/fe51cca4f0df719970555ac3368f62d73ec4590c?w=1), the only real change was removing the `<p>` tags (and changing the extension).

The other advantage, is because it's going through a markdown processor, you'll get things like smart quotes, and automatic HTML entities, not to mention, code highlighting and other cool features not as easily implemented in raw HTML.

No need to merge the pull request per say, but know when moving to a new platform in can be harder to discover the hidden secrets, wanted to pass along one hacker to another as a potential time-saver going forward. :smile:

:beers: and happy blogging!
