Esoteric Language Resources

The internet is an amazing resource for programmers. This is particularly true for programming languages in widespread use. The following graph shows the number of questions on Stack Overflow with a tag for some well-known languages.



There's a huge disparity between mainstream programming languages such as Java and C# and languages associated with artificial intelligence such as LISP and Prolog.

An even greater disparity exists between mainstream languages and expert system languages (that aren't even perceptible on the prior graph unless one zooms in on the far right):



I think this is one of the tallest hurdles to jump for users of esoteric languages. The presence of resources on the internet (discussion forums, documentation, tutorials, examples, etc.) have not reached the critical mass needed for widespread use.
