Ha! I've been working on https://movielandmarks.com/ since 2006 or so. It has gone through various changes (started out as a LAMP stack). It is currently a static site built from a pile of json and a go program to assemble all the parts. I'm the only contributor these days, and only work on it when I feel like it.
At the start I had dreams of selling tons of DVDs via Amazon associates. But I'm terrible at marketing :) So these days it's just a simple site with no ads -- just 1258 landmarks from 322 movies. I sometimes announce new additions on twitter from https://twitter.com/movielandmarks but it only gets about 30 or so visitors a day (mostly bots).
I would also add 'Always set a timeout with -t' both to protect the keys from misuse, and so you don't forget your passphrase when you rarely type it in.
