When your weekend project reminds you how much you need a good camping trip.

Does social media harm everyone?

No. But it harms *most* adolescents, according to a new study.

And not all platforms have harmful effects.

A new analysis of 44,211 daily diaries from 479 adolescents over 100 days finds that the majority of adolescents (60%) experienced small, but consistently negative effects of social media, suggesting that social media use is a notable contributor to mental health issues.

However, a minority (13.6%) of adolescents experienced simultaneously harms and benefits across different dimensions of their mental health.

Exploratory analyses revealed negative impacts of TikTok, YouTube, and Instagram use and positive or null effects of Snapchat and WhatsAp. This means that social media doesn't have to be harmful. https://t.co/UUQZrUf3FL

Come to think of it…

Did any long term successful consumer apps get hype and press *before* they had crazy pmf with a core group of users?

Promoting new ideas and features widely seems unproductive at best, potentially damaging?

@Schwarzenegger Couldn’t agree more! Started @happyfeed 12 years ago to make this practice extremely simple - just one short thing or pic a day - especially love to see end of year summaries and trends over time

@juliapintar Always one step ahead!

@dmiiiitrii Finding myself screenshotting all these for inspo, so good

[Matt Kandler @mattkandler]

@Ryan__Stephen Frame is so good!

Problem is that no one has figured out the right incentives. These all seem great but iMessage is 90% of the way there. Plus getting video sharing, specifically, is tough and hard to ever be on-par as a new app. What’s the NEW thing that attracts people and gets them to stay?

[Matt Kandler @mattkandler]

@8en If it could integrate into a little journaling app, I’d be very down to partner

Otherwise curious where you land… because it’s a space I think a lot about (must be something better than legacy boxes on one side or compilation videos on the other)

[Matt Kandler @mattkandler]

it’s not all about MRR

[Matt Kandler @mattkandler]

@tiffanyyan_x Pretty much @happyfeed is these days - more of a group model than following but it’s an option!

[Matt Kandler @mattkandler]

@helloharuko @MaxonVFX @maxonredshift These are so cool. Always keeping an eye out for art to use in my gratitude app - maybe we could figure something out!

[Happyfeed @happyfeed]

We’ve been featured in Best Journaling Apps by Apple + recently made updates for iOS 26 + optimized videos on Android

Lots left to do before 2026 starts!

@helloharuko Genuinely thought that something was extruding out of your monitor at first glance here
