In most clients the zaps are sorted by amount. So when you zap 10k sats to a post, you can also include some text like “Ive got the best memes” and people who are curious to see who zapped 10k/million will open it and see your text. Thus you got their attention.

Theres also zaplife.lol where people can see zaps and texts. Idk why anyone would keep watching this feed though.

Its aight, nothing next level.
