Receiving a 48 sat zap instead of a like feels amazing :)

So what exactly is a zap signature?

So should I see a count against my post if someone zaps me?

Pretty much given up on running MyNode on my Raspberry Pi. Seems like every time there is an update, it breaks, or I have to mess about getting it to boot again. Feels like I need a more robust solution to run my Bitcoin and Lightning nodes. Plus, I can see a need to run a Nostr relay in the not-too-distant future. Plus some other tools for Mastodon. Any recommendations?
