reddit user posting behavior

This file contains the posting preferences for over 850,000 active reddit users. This data was used to generate the interactive visualization, "redditviz," and will be analyzed in detail in an upcoming research article. The file is organized as follows: Each line is an entry for an anonymous user. Each user was randomly assigned a unique ID, which is what shows in the first entry of each line. Following the user ID, separated by commas, are the subreddits (i.e., interests) that the user regularly posts in. In order for a user to be considered "active" in that subreddit, they had to post or comment there at least 10 times in their last 1,000 posts and comments.
