Show HN: Engagement Experiment – Venmo vs. Cash App

https://wrpolls.com
1•wr639•1h ago
I built a very small internet experiment to measure engagement between payment platforms.

The idea is simple:

Venmo vs Cash App.

Participants can tap $1 on either platform and it counts as an engagement signal.

There is:

• no product • no donation • no reward • no exchange

The $1 simply acts as a friction signal to measure which community shows up.

The site displays live engagement data including:

• platform split • time-of-day activity • engagement heatmap

It's basically a real-time behavioral experiment.

Curious to see which community participates more.
