Viral score

Based on absolute engagement — the platform doesn’t expose follower counts here, so large accounts score higher.

From likes, comments.

Why it worked

Written from experience rather than as advice, which is harder to argue with.
Short enough to read in full without expanding, which removes a step before the point lands.
Short sentences keep the pace up, so the reader never has to re-read a line.

The mechanics

Hook: Announcement
Structure: Hook → Landing
Style: Conversational paragraphs at a steady pace.
Tone: corporate
Written for: Product teams

If you haven’t used Grok 3 “Sexy” 18+ mode, drop everything and try it. I can’t explain how unbelievably messed up this is (and I can’t post a video). This may single handedly bring down global birth rates. I can’t believe Grok actually shipped this.

AirPods Max 2 - Same design - 1.5x stronger noise cancellation - New amplifiers - H2 chip, which enables several things, like: - Live translation, camera remote - Still $550 t.co (I hope this puts into perspective how insane Macbook Neo for $499 is lol)

Instagram has unveiled Instants. The new feature allows users to share uneditable photos with their close friends and mutual followers. Instants disappear after being seen, (and after 24 hours), and cannot be screenshotted by others.
