I still use likes and other reactions, depemding on the functionality of the client.

But I also use 8-sat zaps. Why? 8 is a lucky number in some cultures, especially regarding money. 8 has some significance in the CS world as well, as 2 cubed.

I also sometimes use 22 and 68. My son's favorite number, and one of my favorite numbers. Not entirely accidental these are one off from popular meme numbers. My birthday is 419 if I need a higher number, I guess. But nobody needs to be zapped that much of my children's inheritance.

For the most part, likes & replies. For polls, 1 sat. For zapathon and when I'm feeling cute, 8. For when I really spent some time or got some value out of a note, 22 or 68.
