The cool thing about Reddit is that you can subscribe to just the subreddits you like, and ignore everything you don’t. The smaller, more specialized subreddits are the best, but they’re harder to find. The new tool sayit helps you find them.
Sayit shows a network map of subreddits, judging their similarity by the number of mutual commenters. So if I look up r/seashanties, I see that it’s similar to r/IrishMusic and r/tinwhistle, because a lot of the same redditors write posts and comments on all of these subreddits. (It’s also “similar” to a couple of unrelated video game subreddits, just because those also share a lot of the same members.)
This is a great way to find subreddits that tackle the same topic in different ways. If you subscribe to r/rpg, the sayit graph recommends the subreddits for specific tabletop games like r/Shadowrun, r/DungeonsAndDragons, and r/Pathfinder_RPG. But it also links to:
Plus subreddits about specific settings, editions, and scenarios within D&D and other games. It’s not exhaustive—for example, there’s no link to the small but excellent r/rpghumor—but it can surface connections that you wouldn’t find on Reddit itself.
Click a subreddit to see some recent posts. Double-click a subreddit to start a new graph around it. If you open the r/rpg graph and double-click on r/magicTCG (a big subreddit dedicated to Magic: The Gathering), you’ll see subreddits like r/ModernMagic, r/custommagic, r/spikes, r/gwent, r/BadMtgCombos, r/magicthecirclejerking, r/CompetitiveEDH, and r/hearthstone.
With Sayit you can dig deeper into a topic with more specific subreddits, or find related topics that share a readership. You could look up a political subreddit and find others for people of the same political persuasion, or wade into ones at different points on the spectrum. Look up your city’s main subreddit, and you can find subreddits for housing, jobs, restaurant recs, local politics, or even specific neighborhoods. It’s like Reddit’s subway map.
