Default subreddit

A default subreddit was a subreddit that users were automatically subscribed to when they created a registered account for Reddit. The concept of a default subreddit was formally ended on May 31, 2017 by admin decision. 
The user had an option to unsubscribe from these subreddits after they registered on Reddit. However, this auto-subscribe practice led to many of these subreddits becoming some of the most-subscribed on the platform. 
==Admin announcement==
Hi folks,
TL;DR People creating new accounts won't be subscribed to 50 default subreddits, and we're adding subscribe buttons to Popular.
Many years ago, we realized that it was difficult for new redditors to discover the rich content that existed on the site. At the time, our best option was to select a set of communities to feature for all new users, which we called (creatively), “the defaults”.
Over the past few years we have seen a wealth of diverse and healthy communities grow across Reddit. The default communities have done a great job as the first face of Reddit, but at our size, we can showcase many more amazing communities and conversations. We recently launched r/popular as a start to improving the community discovery experience, with extremely positive results.
New users will land on “Home” and will be presented with a quick tutorial page on how to subscribe to communities.
On “Popular,” we’ve made subscribing easier by adding in-line subscription buttons that show up next to communities you’re not subscribed to.
To the communities formerly known as defaults - thank you. You were, and will continue to be, awesome. To our new users - we’re excited to show you the breadth and depth our communities!
Thanks,
Reddit
