I like Walker's idea of zapvertising. Blockstream sent me 1000 sats for engaging with their post about Jade on Nostr. I ended up buying the device. All sats are precious but that's a ridiculously low customer acquisition cost. 

This would be more zap for PR but similar.

Yeah that would be great PR for companies.

From time to time there are bitcoin related businesses  who discuss their products here on Stacker News. If any of them choose to participate it is only fair that they get some free publicity by letting everyone know that they contributed in a reply. I know many people prefer to donate anonymously, but this could be an effective  way to support the community, get visibility,  and support a worthy cause.

*Please zap Anita, not me.
