Philipp Singer, Fabian Flöck, Clemens Meinhart, Elias Zeitfogel, Markus Strohmaier
TL;DR
The paper asks how Reddit’s submissions, attention, and perception changed as the platform grew. Analyzing almost 60 million submissions over five years, it finds increasing topic diversification alongside concentration on a few domains and growing self-referential content.
Problem
The study addresses how Reddit’s user submissions and the community’s allocation of attention and perception changed over five years.
Method
The authors conduct a longitudinal analysis of almost 60 million Reddit submissions from 2008–2012, supplemented by a user survey.
Results
Reddit diversified into many specialized sub-communities while submissions and attention increasingly concentrated on Imgur.com and self content.
Takeaways & Limitations
Reddit increasingly functions as a self-referential community that focuses on and reinforces its own image- and textual content over external sources.
Takeaways & Limitations
The study is a preliminary analysis, and its auxiliary survey has limited sampling and self-selection.
Abstract
from arXiv · showhide
In the past few years, Reddit -- a community-driven platform for submitting, commenting and rating links and text posts -- has grown exponentially, from a small community of users into one of the largest online communities on the Web. To the best of our knowledge, this work represents the most comprehensive longitudinal study of Reddit's evolution to date, studying both (i) how user submissions have evolved over time and (ii) how the community's allocation of attention and its perception of submissions have changed over 5 years based on an analysis of almost 60 million submissions. Our work reveals an ever-increasing diversification of topics accompanied by a simultaneous concentration towards a few selected domains both in terms of posted submissions as well as perception and attention. By and large, our investigations suggest that Reddit has transformed itself from a dedicated gateway to the Web to an increasingly self-referential community that focuses on and reinforces its own user-generated image- and textual content over external sources.
1. INTRODUCTION
This study examines how Reddit’s submissions, community attention, and perception changed over five years using almost 60 million submissions. It finds increasing topic diversification alongside concentration on selected domains and self-generated content.
- The study analyzes Reddit’s evolution from 2008–2012 through user submissions, voting, and commenting patterns.The dataset contains almost 60 million submissions.
- Reddit developed an increasing diversity of topics alongside concentration toward selected domains and submission types, especially self and image posts.
- The authors characterize Reddit as shifting from a gateway to Web content toward a self-referential community focused on its own user-generated content.
2. DATASET AND METHODS
The study analyzes all Reddit submissions from January 2008 through December 2012, categorizes linked content, and supplements the analysis with a limited user survey.
- The dataset covers all Reddit submissions from January 2008 to December 2012, with metadata collected after voting activity had settled.
- The analysis includes 58,874,22 submissions across 125,662 subreddits and 4,910,850 authors.
- The authors manually classified the 100 most frequently submitted domains, representing 69% of submissions, into six content categories.
- A short auxiliary survey supplemented the analysis, but its limited sampling and self-selection must be considered when interpreting results.
3. DIVERSITY AND SELF REFERENCE
Reddit’s submissions diversified across an expanding number of subreddits while concentrating around a few domains, especially self posts and Imgur, with images and self-referential communities becoming increasingly prominent.
- 3.1 The diversification of subreddits: The number of active subreddits rose from 213 at the beginning of 2008 to 32,202 by the end of 2012.
- 3.1 The diversification of subreddits: By the end of 2012, the 20 largest subreddits contained less than 40% of submissions, compared with around 80% in mid-2008.
- 3.2 Towards self-reference in submissions and their linked domains: Imgur.com’s share of submissions increased from 0% in mid-2008 to 26.6% at the end of 2012, while YouTube and Quickmeme also expanded.
- 3.2 Towards self-reference in submissions and their linked domains: Despite subreddit diversification, linked submissions concentrated increasingly in self and Imgur.com, with the URL Gini coefficient rising from 0.78 in mid-2008 to 0.95 at the end of 2012.
- 3.3 A shift to “self” and images: Image submissions grew, and by the end of 2012 textual content and media content were almost evenly balanced.
- 3.3 A shift to “self” and images: Self posts became especially concentrated in r/AskReddit, where users posed open-ended questions for collective discussion.
4. ATTENTION AND PERCEPTION
Reddit’s attention and perception increasingly concentrated on a small set of subreddits, domains, and content types. Image posts attracted most votes, while self submissions drove an especially large share of comments.
- The study uses voting as a proxy for perception and comments as a proxy for discussion affinity, while average scores rose over time.
- More than 70% of all votes at the end of 2012 went to the top 20 subreddits.
- Users’ comments increasingly concentrated on self submissions and Imgur, with Imgur’s comment growth exceeding its submission growth.Self submissions remained the primary driver of conversations.
- Image submissions received about 85% of all votes in late 2012, up from about 16% at the beginning of 2008.Self submissions received around 8% of votes in late 2012, down slightly over time.
- Self submissions attracted 50% of all comments at the end of 2012, up from about 4% at the beginning of 2008.The results associate image posts with voting attention and self posts with commenting attention.
5. DISCUSSION
Reddit diversified into thousands of subreddits while concentrating submissions and attention on Reddit itself, Imgur, images, and self posts. The authors interpret this pattern as a shift from linking outward to community-focused self-reference.
- Subreddit diversity increased, but linked domains became concentrated around Reddit itself and Imgur, followed by YouTube and Quickmeme.This concentration aligned with the growth of image and self posts.
- Self submissions increasingly centered on questions for the community and ironic discussion of Reddit, strengthening the platform’s self-referential character.The authors also describe self posts as increasingly discussion- and socially oriented.
- Images often conveyed personal messages or references, while image posts received more votes and scores and self posts received more comments.The authors suggest images require less cognitive effort to judge, whereas text posts are more likely to stimulate discussion.
- Although the number of distinct linked top-level domains increased, images and self posts occupied an increasingly large share of available submissions.
- Users increasingly encountered self-referential content because of its volume, voting preferences, and a possible self-reinforcing cycle of exposure and participation.
- The authors describe Reddit’s community aspect as increasingly important, with images and self posts becoming prime means of communication among members.
6. RELATED WORK
Related work examined how submission characteristics and resubmission histories affect Reddit popularity. The supplied passages do not provide a broader synthesis of this literature.
- Prior studies examined how titles, submission times, community choices, and resubmission histories affect the popularity of Reddit content.One study found that good titles positively affect popularity, while another found identical links can be ignored before later becoming popular.
7. CONCLUSIONS
The paper’s conclusions emphasize Reddit’s transformation from a gateway-oriented platform toward a more self-referential community. They frame the study as a preliminary analysis and encourage deeper research on Reddit and comparable platforms.
- The study identifies increasing topic diversification alongside concentration in selected domains and content types, especially self and image submissions.
- The authors conclude that a rapidly growing community with extensive user freedom can dramatically change its nature and focus over time.
- They characterize the analysis as preliminary and encourage more in-depth studies of Reddit and comparable community platforms.
