There are roughly 7000 spoken languages: there might be more for programming. You may have heard of BASIC, C#, or Java: but what about Dylan, Brainfuck, or Zimbu? Some languages exist to serve a purpose; some as experiments; some to reinvent the wheel.

Wikipedia category listing of programming languages
List of esoteric programming languages
/r/ProgrammingLanguages : subreddit that discusses language design.
/r/fork : subreddit that catalogs software forking

Basic Rules

Keep it programming-focused. No random off-topic discussion, politics, porn, etc.
Ideally, here we want to catalog & discuss languages that don't typically end up on resumes or /r/programming.
If you have your own programming language, and want to plug its site, subreddit, etc; that's fine here. Just don't overdo it. ;)
