Reddit’s subreddits cover, quite literally, an infinite amount of different topics. But which of its subreddits are the biggest?
Sure, Reddit is known for subreddits such as /r/pics and /r/aww, but in actuality, many of the lesser-known subreddits are much bigger than you think.
By tabulating the data of 37,561,369 total sitewide Link submissions, from 12/18/2011 to 9/26/2013, I created a tree map of the Top 100 subreddits by the number of Link submissions to that subreddit.
In the tree map, the size of the rectangle and the saturation of the blue color indicate the relative size of the subreddit.
Unsurprisingly, the default subreddits, which all new users are subscribed to, are ranked mostly at the top. However, subreddits such as /r/POLITICO, /r/leagueoflegends, and /r/trees are higher (no pun intended) than most of the default subreddits.
And then you have the meta subreddits such as /r/ModerationLog and /r/reportthespammers, showing that people spend a considerable amount of time talking about Reddit itself.
Gaming has a very significant presence as well, with /r/Minecraft, /r/DotA2, and /r/tf2. (notably for the latter two, the trading subreddits for the respective games have significantly more link submissions than the subreddits themselves.)
It’s worth nothing that these Top 100 subreddits only account for 46.3% of all Reddit link submissions. Even the Top 500 subreddits only account for 66.2% of all Reddit submissions. The density of link submissions clearly follows a long-tail distribution, where most of the content is centralized from the top subreddits. It’ll be interesting to see if Reddit is able to utilize that treasure trove of links in the future.
I am currently looking for a job in data analysis/software engineering in San Francisco. If you liked this post and have a lead, feel free to shoot me an email.
Since I currently do not have a full-time salary to subsidize my machine learning/deep learning/software/hardware needs for these blog posts, I have set up a Patreon, and any monetary contributions to the Patreon are appreciated and will be put to good creative use.
