front matter of posts.md

Every new post (_post) needs a front-matter. The front-matter of a page/post is the "YAML" formatted part at the top of almost each page within Jekyll static site. For the ruby.org.ve site, these are the needed front-matter attributes for it to work properly:

---
layout: post
title: Reactivando la comunidad
author: Pedro Perez # (optional attribute)
author_twitter: pperez # (optional attribute)
tags:
- comunidad
- hangout
- rubytuesdays
---

note: It's possible to write posts for ruby.org.ve using prose.io, but, the user must manually fulfill the metadata attributes within prose. These attributes represent each value of the YAML front-matter previously displayed.
