Can we make it a thing on nostr, that we don’t openly discuss or say who or what we are personally voting for?

In my opinion, that information is private, and it should stay private.

Two things that should never be public information or ever revealed.

1. The size of your stack 
2. Your voting choices

This your private information, and it is for you and you alone

Stack sats, do good things and stay true to yourself and others.
