Created https://flexlists.com 15 years ago to scratch an itch. For me it already succeeded; many happy users for over a decade but it is not a success by any going standard of money or attention and I do not care.

Create a programming language with a friend currently; again to scratch an itch. It will be launched somewhere 2022 hopefully but if we are the only users, it is fine. If not, so much the better.
