Duolingo's most powerful re-engagement notification is one sent after five days of inactivity stating, "these reminders don't seem to be working. We're going to stop sending them." This passive-aggressive message makes users feel the app is "giving up on them," which is surprisingly effective at getting them to return.

Mindless scrolling seeks a "fake" dopamine hit from passive consumption. By contrast, structured, intentional engagement—like sending five meaningful messages—creates "real" dopamine from accomplishment and relationship building. This purposeful activity can paradoxically reduce overall screen time by satisfying the brain's reward system more effectively.

Social media algorithms can be trained. By actively blocking or marking unwanted content as "not interested," users can transform their "for you" page from a source of distracting content into a valuable, curated feed of recommended information.

TikTok's new 'wellness' features, which reward users for managing screen time, are a form of corporate misdirection. By gamifying self-control, the platform shifts the blame for addiction from its intentionally engaging algorithm to the user's lack of willpower, a tactic compared to giving someone cocaine and then a badge for not using it.

Users can now manually add or remove interest categories to customize their feed algorithm. This allows creators with a well-defined niche to be directly recommended to users who have explicitly expressed interest in that topic, leveling the playing field for smaller accounts to get discovered.

The true cost of social media isn't just the time spent posting; it's the constant mental energy dedicated to it—planning content, checking engagement, and comparing yourself to others. Stepping away frees up significant cognitive "white space," allowing for deeper, more strategic thinking.

When platforms like Instagram roll out a new feature, such as the awkward long horizontal format, marketers should adopt it immediately. Platforms aggressively push new features to drive adoption, rewarding early adopters with increased visibility and reach, even if the feature itself is disliked by users and creators.

The narrative that AI-driven free time will spur creativity is flawed. Evidence suggests more free time leads to increased digital addiction, anxiety, and poor health. The correct response to AI's rise is not deeper integration, but deliberate disconnection to preserve well-being and genuine creativity.
