50 reactions, 50 pushes, and the batch that still sends 5

transcript

Kabir's split gets 50 reactions. In four minutes. His phone buzzes 50 times. That's not a feature. It's a bug. One line saying Arjun and 49 others reacted? That's the feature.

Easy fix, right? Hold them, and send one summary. Flush when 10 reactions pile up. Or 300 seconds after the first one. Whichever comes first. Done?

Here's the catch. A reaction lands every 4 point 8 seconds. The 10th lands at 43 seconds. Push one. The 20th at 91 seconds. Push two. A burst keeps tripping the count. Five pushes, not one.

So flip it. Send the first one at once. Hold the other 49 for 300 seconds. Send one summary. Kabir hears right away. Then it goes quiet.

No batching: 50 pushes. The hybrid: 5. And the first one waits 43 seconds. First at once, then one summary: just 2. The first is instant.

Batching saves the sends, not just the screen. For social, ship that one. Instant feedback. Then quiet.
