>If you have so few that you can maintain a list, it kinda proves OP's point

OP didn't really make a point. He just said that he would like posts about lisp being used in production

> Also as an addendum to his point, what about projects being written in the last decade or two?

It's a niche language so it's pretty pointless throwing lists of all CL projects in production at people. Instead I suggest you say what domain interests you and maybe someone who worked in your domain will be able to give a more meaningful response

Wow I forget how old my operating system is given how "modern" it feels and that to this day nothing even comes close to it
