Observation about my tweets - exactly 280 characters - means editing and sharper thoughts 🧠

This is obvious once you know it.

Whenever my tweet is exactly 280 characters - it means I was polishing, finetuning, editing, ensuring it has exactly the amount to fit - maybe promote it more as I really put the effort in?

Time on editing box can be a good metric too, although easy to gamify, so it the exact 280 characters. But if you combine it with detecting keystroke patters = then the signal is relatively strong.

🔧 DIY / Technical Setup

If you're a developer or builder:

1. Capture typing data in JavaScript (e.g., keypress, keydown, keyup events).

2. Extract features:

   • keydown to keyup duration
   • Time between consecutive keydowns

3. Train a model (e.g., random forest, SVM, or neural net) on your patterns.
