About this Site
This site exists to promote languages which are in development or have not yet reached a wider audience. This includes languages that do not ever intend to reach a wider audience, but are being developed for fun, learning, academdia or for no good reason at all.
As far as I am aware, there are pages for esoteric languages, joke languages, and all kinds of popular languages, but these generally discourage the sharing of languages that are just starting out. So, this page exists for people to share toy, hobbyist, and any fledgling languages people may be working on.
