		j represents the number of articles that will be checked, it should be set based on the 
		number of featured articles we want to show (i). More articles to show = more times to check.
		Remember that one blog among all the blogs could contain all the most recent articles.

		here is where the article should be output, example: 
		<h1>{{ latest_article.title }}</h1>
		<h3>{{ latest_article.published_at | date: "%c" }}</h3>
		These will output in descending order, most recent article among all the blogs first.
		Alternatively we could store the article here for use elsewhere, example:
		{% if i == 0 %}{% assign featured_post_1 = latest_article %}{% endif %}
		{% if i == 1 %}{% assign featured_post_2 = latest_article %}{% endif %}
