I always want to keep you in the know. You may have heard of Reddit but never really got into using it. Unlike other social media sites, Reddit is more group- or topic‑focused.

Think of it as various rooms of people sharing and talking about one particular topic. About 73.1 million folks use it daily, and there are 2.2 million groups you can check out. If you’re totally new to Reddit, here’s everything you need to know.

Reddit, set … go!

Reddit looks and feels like an old-school forum or message board: Members, or Redditors, can create and post to individual forums called subreddits.

Posts have comment threads attached where others can weigh in. You'll see little arrows on posts and comments, too — these are upvotes and downvotes. That’s the crowd-based ranking system Redditors use to weed out spam and promote the good stuff.

You don't need an account to browse …

But it’s free and comes with a few perks. For one, you can post or respond to others’ threads and earn karma, a points system based on how many upvotes your post or reply gets.

You can also subscribe to subreddits to get the latest posts on your Reddit homepage — look for that big Join button.

💡 Privacy tip: Don’t use identifying traits in your screen name! Reddit accounts are anonymous by default. If you include clues like your city or nickname, it’s easier than you might think for people to ID you.

Lingo to know

Don’t let the acronyms scare you. Here are some of the most common ones on Reddit:

Must-follow subreddits

🔎 One more thing: If you’re ever wondering if something is a scam, use the search box on Reddit. Odds are, someone somewhere has an opinion about it.

🤔 So, what phone does ol’ Bill Gates use? A Samsung Galaxy Z Fold 4, gifted by the chairman of Samsung himself. I wonder if he has a good voice.

🚨 TikTok vape dealers: TikTokkers are illegally selling vapes to kids using secret codes to trick parents. Red flag phrases include “elf bundle” (i.e., an Elf Bar vape), “ALL FAKE” (used to slip past Communist China censors) and “#noID” (no identification required). If your kid recently got hair scrunchies, beauty products or candy in the mail, check the package.

Tesla, meet train: A Tesla driver nearly crashed into a moving train when his car failed to brake in self-driving mode. His dashcam shows him swerving at full speed just in time. Just three years ago, Tesla's image rank (a measure of their brand reputation) was eighth among the top 100 companies. Now, it’s plummeted to No. 63. Can’t imagine this is helping.

👯 #Twinning: At age 66, Devlin Donaldson used a “digital twin” to reverse his Type 2 diabetes. OK, not a literal twin — the Twin Health app, which uses insights from your diet, activity, blood glucose levels and more to give you hyperpersonalized advice. The instant feedback helped Donaldson lose 40 pounds and go off medication. This is why I love tech, folks!

Child ID theft is on the rise: If you’re not on the lookout, you might not catch it for years. When your kid goes to rent their first apartment or get a student loan, they could find they’re already thousands of dollars in debt. Protect your kid’s credit now — I’ve got steps on how to do it on my site.

💃 Finally, some respect! TikTok teens are asking their moms to bust out their best ‘80s dance moves, and for once, it’s not for laughs. The videos have racked up tens of millions of views, and Gen Z is genuinely impressed. What’s your favorite ‘80s dance hit? Mine’s “Take on Me” by A‑ha!

🌞 Sun-spiracy: Some popular influencers don’t believe the sun causes skin cancer (WSJ, paywalled); instead, they blame sunscreen. Research proves sunscreen protects you from cancer — it doesn’t cause it. I posted a pic of me by the pool the other day. I can’t believe some people didn’t get my sunscreen pun in the caption. Please tell me you do!

Over Wordle? There’s a new game hidden on your iPhone called Quartiles. You score points by making as many words as you can from three or four lettered tiles. The iOS 17.5 update includes the game for all Apple News+ subscribers (you can get a free three-month trial if you don’t have it already). To find the game, open Apple News and search for Puzzles > Quartiles.

Mute yourself when you’re on hold waiting for customer service help. You know that message about how what you say may be recorded for training purposes? They don’t just mean when you have a rep on the phone.

Didn’t catch that: Always missing the audio? On your phone, look in the Accessibility settings for Live Captions, and turn it on. Whenever speech is detected, you’ll see the transcription in the center of your device’s screen.

Quick change your settings: On a PC, press the Windows key + A to get to most commonly used settings, like volume, display brightness and Wi‑Fi. On a Mac, you’ve gotta click Apple menu > System Settings.

It’s not you screwing things up: If your Apple TV screensavers are on the fritz lately, YouTube’s to blame. Turns out, when you have the YouTube app open when your TV falls asleep, it’ll automatically override your screensaver with its own — so close the YouTube app.

Silence is golden (unless you have a toddler): Did you know you can instantly silence incoming calls on your smartphone by pressing the side button (volume up or volume down) once? Yup! It’s a tech secret the pros know — and now you do, too. You’re welcome!

Flies are so annoying. You need these on hand at all times:

“We Camelot last year and love it here!”

The answer: A.) “The Goonies.” A sealed VHS copy of the Spielberg classic shot in Astoria, Washington, sold for $125,000 on eBay. Sealed original VHS copies of “Back to the Future” and “Ghostbusters” have each sold for $75,000, while a VHS copy of “E.T.” went for $40,000.

🏀 Did you know Steven Spielberg and John Williams play basketball together? He shoots, he scores! (You’re welcome, movie nerds.)
