Why much more articles about Haskell than popular ones like Java on HN?

Haskell is much more interesting as a language than Java. And Haskell has its supporters within the HN community who are willing to inform those unfamiliar with the language.

Java is a supremely boring language, and was when it started. It is a pure industry project, it will eventually go the way of COBOL; although interfacing with it from other languages will become more common.

The most interesting part of java, was the JVM, which has been subject to plenty of attention.

I think it's a few different reasons:

- There is a lot about Java elsewhere

- Java isn't so interesting and is probably used at a lot of HNers for work.

- Java doesn't represent the future of programming to many, though it's advances in tandem with keeping backwards compatibility are respectable.
