Reddit is a large and influential social news website. You may remember it was the first website to suggest and commit to the Stop Online Piracy Act (SOPA) blackout in January 2012.
Being a social news website, it revolves around its users submitting content and then having other users vote and comment on this.
This generates the link's ranking. Every link has two arrows next to it, one pointing up (named an upvote) and one pointing down (a downvote). Clicking these allows Reddit's users to vote and see the link's current standings.
Redditor is a term used to describe a registered user of Reddit that contributes to the site either by submission or comment. Each registered user has their own 'front page', which is a compilation of the links that are submitted to the subreddits that the user is subscribed to.
The best way to comprehend the relation between Reddit, the Redditor's front page and subreddits is to imagine a large group show-and-tell scenario.
Imagine that there are groups of people sorted by their main interest sat around vast tables with large banners above them briefly describing what the interest is. Each person has brought something that they find of some worth which is related to the interest.
This could be anything at all from a hilarious anecdote to an interesting scientific discussion to a cute and adorable picture of a cat. There are over 100,000 of these groups of people, each having their own set interest and taste.
These groups now lay out and order all the items that the individuals in their group have brought and each table now has their own ranking for said items. The tables are known as subreddits.
Now, imagine an even bigger table. Several times bigger than the others. One with gilded edges if you'd like. The banner above this table reads "Redditor's front page".
The Redditor - to whom this front page belongs - selects which subreddits (s)he'd like to hear from. Once they've done this, all the items from the subreddits are combined to create one grand master ranking list of items that this individual Redditor is interested in.
In reality, the ranking system is slightly more complex than this and sadly slightly less gilded but this will be explained later in this article.
