Redditor douglasmacarthur studied the top 200 most active communities on Reddit and decided that categorization was necessary. On May 29, he posted his project to r/TheoryOfReddit, a community designed to study and discuss the site.

“While observing how much difficulty moderators of large subreddits have directing users towards the appropriate ones, I concluded that one of the major reasons for this is the difficulty new users have accessing info on non-default subreddits. reddit.com/reddits[1] is tedious to go deep into,” douglasmacarthur explained in a comment.

Using information gathered from stattit.com, douglasmacarthur arranged the top 200 subreddits into 14 categories. He plans to expand the project to the site’s top 500 communities and break down the categories even further.

He omitted pornographic subreddits from the list but, when asked, compiled them into an offsite post. The list is topped by the NSFW subreddit r/gonewild, which is the 20th most active community on the site.

Many of the most active subreddits fall into the “Entertainment” realm, which douglasmacarthur has broken into the sub-categories of “Gaming,” “Television,” and “Other (Movies/Music/Franchises/Misc.).” The most active subreddit on the site, r/pics, is one of many in the “Images, GIFs, and videos” category.

The “Places” and “Race, Gender and Identity” categories in douglasmacarthur’s list, on the other hand, boast the fewest number of active subreddits. In fact, none of the top 10 most active subreddits are found in either category.

Redditors in the thread shared their thoughts on specific points showcased by douglasmacarthur’s newly-created categorization.

“This is a great start. As a relatively new user, many of these subreddits were unknown to me, and as you said, sorting through the lesser-known subreddits can be a hassle. Thanks for working on this,” Lhopital_rules commented.

“Cool to see r/android is the first big technology subreddit after the obvious r/technology,” emohipster commented.

Redditor q9rtn took it a step further and made multireddits out of the subreddits listed in each of the 14 categories.
