Is something missing in single.html?

[nonstopnate]

Love the theme and all of the work put into it, just wondering if something is missing in layouts/_default/single.html

Lines 63 and 69 refer to .Site.Params.article.showRelatedPosts. I assume it wasn't supposed to be .Site.Params.article.showRelatedContent .
Was showRelatedPosts going to be a separate parameter?

Is there a bracket/parenthesis missing on line 72?

Also is something missing where it says "sd"? Or was it something planned but not yet implemented?

{{ if .Site.Params.article.showRelatedPosts | default false }}
 sd 
{{ end }}

Forgive me if they're dumb questions, new to Go and only been playing with Blowfish for about a week.
