I’ve rarely seen an increase in traffic due to Reddit with one exception. When Sarah Gooding published an article announcing WordPress had adopted the Sass CSS Pre-processor WPTavern experienced a large bump in traffic. There were over 20 upvotes on the WordPress subreddit along with a few comments. Because of the technical nature of the article and the technology focused users of Reddit the article did well.

At the time the 'adopted' Post went up (mid-November), the Drupal community was freshly-electrified by the formal announcement of a fork, spearheaded by prominent members of the fraternity.

A central element of that (ongoing) breakdown at Drupal, was its adoption of SASS.
