The list of the best learning and educational subreddits

Reddit is one of the most popular social news aggregators, online community forums and discussion-rating websites. For years, Reddit was one of my main sources for different life hacks and articles on the subjects I’m interested in. Today, I don’t use it regularly anymore. I visit Reddit only approximately once a month to skim the most popular posts and feel the pulse of different communities.

If you wonder why I don’t use Reddit daily anymore, it’s because I’ve unplugged myself from all “fake” reading and learning, where you only skim through dozens or even hundreds of articles and not much knowledge really stays with you. Today I strive to get the most out of my learning time by reading books and through deliberate practice (here you can find a guide on how to learn).

The bottom line is that in most cases, it’s better to read ten pages of a quality book than to skim hundreds of mediocre articles on aggregators. Next to that, there are hundreds of new articles published every day, which can make you very nervous if you are a perfectionist who would like to read everything in your newsfeed.

In spite of that, Reddit is one of the few social networks that has really useful subreddits and can be worth your time, if you know how to use it in a productive way.

A few words about Reddit and why to use it

If you are new to Reddit, Reddit consists of thousands of communities (subreddits prefixed with /r/) that focus on different topics and interests. Each subreddit has its own moderators and the subpage is designed slightly differently from the others while the general Reddit layout is the same. Anyone can start a new community and that’s why there are so many subreddits (850,000+).

Many subreddits can prove to be:

• a great community to motivate you,
• a good place to get an overview of a specific topic,
• an excellent source of knowledge (but not as good as books),
• a place to get many ideas quickly,
• the way to feel the pulse of different communities and what’s new.

People post their thoughts and opinions in a simple text format to selected subreddits or they only post interesting links, and then a discussion evolves. Each item is posted to one subreddit and then gets upvoted or downvoted, and that influences the ranking of the posts.

That means that the community decides what’s important and what isn’t. Posts that get the most upvotes rise to the top of the subreddit. Downvoting and upvoting is what differentiates Reddit from casual forums.

• Link post: Title with link to a website (article, news etc.)
• Text post: Title and body of text (there can be links in the text)

You can sort posts by hot, new, rising, controversial or top (day, week, month, year, all time). Each subreddit also has its own admins ([A] next to the username), community rules and often general information about the subreddit in the sidebar.

One more important term you have to understand is Reddit karma. There are two different Reddit karmas – comment karma and post karma. Post karma is the sum of all upvotes (minus downvotes) from the links and text posts you submitted to different subreddits. Comment karma is the same but for comments. So the more active member of the community you are, the more karma you get.

One big downside of Reddit is that the site looks a little bit geeky, with a bunch of links and weird design, so it takes some time to get used to it. Especially when you open the default first page, things can be pretty confusing and nothing seems interesting if you aren’t ultra-geeky.

People on Reddit also tend to be very critical and opinionated. Consequently, you have to be open to different perspectives and accept it when people write a few harsh words on your account.

But trust me, if you create an account, unsubscribe yourself from a few default subreddits and subscribe to a few quality educational subreddits, your first page will become much more interesting and Reddit can become an important app in your infostructure and knowledge source arsenal.

Make sure you don’t start wasting your time on Reddit

Several subreddits, even the popular ones, can be a pure waste of time. I suggest you completely avoid them. The number one rule when it comes to Reddit is: Don’t waste your time on mental masturbation subreddits.

Not even on a single one of them; because you can quickly get drawn into unproductive browsing. The default front page of Reddit (before you unsubscribe from the default subreddits and subscribe only to the ones of your choosing) can become one of them – if you don’t rearrange it correctly.

The front page shows the most popular posts from the subreddits you are subscribed to. So choose the subreddits you subscribe to very carefully and make sure you rearrange the first page (by unsubscribing and subscribing) as soon as you create your account.

There are two general ways how to browse Reddit:

• Browse the front page, where the most popular posts from all the subreddits you are subscribed to are aggregated
• Go to a specific subreddit to read more new posts, browse popular past posts or check information in the sidebar

Besides curated knowledge and a strong community, there is one more big benefit of Reddit. Reddit can present a great transitional path from using internet for wasting time (email, news, social networks etc.) to slowly building your attention span by being a part of the community to the point where you can finally start using the Internet for growing and learning.

If you are serious about learning and making the Internet your tool for personal growth, here is how the transition usually looks like:

1. You use internet only for fun, communication and mental masturbation (outside the working time) – unfortunately that is where most people stay forever.
2. From time to time, you read an educational post that accidentally pops up in your social networks.
3. You subscribe to a few interesting blogs or join an interesting subreddit, but you only skim the headlines and then you skim an article or two.
4. The tipping point: You actually read a whole article or two of them, and think about the ideas in the articles and how to apply them in your everyday life.
5. You start reading books. It feels weird because there is no scroll-down function or back button.
6. You realize how much more you are gaining from real reading and learning, and slowly you are leaving all the mental masturbation things behind. You limit the time spent on social networks, online communities and aggregators.

As you can see, Reddit can be a great first step towards nurturing your curiosity and starting with real online learning. That’s why I decided to gather all the best educational subreddits in one place. So you don’t have to search for them and you can immediately subscribe to the ones that interest you the most. These are the subreddits that are worth your attention.

Educational and life mastery subreddits you have to know

Reddit has more than 850,000 subreddits (many of them are dead or small), 11,500 active communities and 230 million users. For some topics, there are even competing subreddits with many members, and others have small inactive communities.

I tried to list all useful educational subreddits, even if they are small or not very active. They are ranked from subreddits with the most members (approximate number) to the ones with the fewest members (but that doesn’t necessarily mean that bigger is better).

I suggest you check all the different topics you are interested in and then decide which subreddits you will subscribe to. You can subscribe to dozens of them, there are no limits to worry about. And you can always unsubscribe from the subreddits later if you find them boring.

If you don’t have a Reddit account yet, it’s easy to open one. And it takes one click to subscribe or unsubscribe to a subreddit. They also have a great mobile app (iTunes, Google Play) so you can read interesting articles and enjoy the online community life everywhere you go.

If you are looking for additional ideas about which subreddits to subscribe to:

• Check sidebars of different subreddits – related topics are usually listed
• Use the search bar in Reddit to find interesting topics
• Many subreddits are advertised on other subreddits
• Pay attention to the Subreddit of the day
• And here is a big directory of subreddits

And now the main part.

Below is a list of educational and life mastery subreddits worth following. Select the ones that interest you and make sure you follow them. I skipped all the news subreddits or semi-educational ones, and instead focused on the ones that encourage real learning, knowledge sharing and critical thinking on specific topics.

The links in this article lead to subreddits organized by the most upvoted posts of all time, so you can quickly get a glimpse of what kind of content is usually posted in the subreddit.

IMPORTANT NOTICE: The links don’t work on mobile phones (because of sorting). Please click the links on a desktop computer. Reddit should fix the bug soon.

Recommended subreddits are sorted into different topics:

1. General
2. Learning and skills
