Seriously? Here is the latest example on scala-debate, just two months ago, where he went so far off the deep end that Martin himself had to step in and tell him to cool down:

He dishes this kind of abuse on a regular basis on lists, irc (especially #scala) and sometimes even on his own Twitter feed.
Anyway, back to the topic at hand: yes, I know the theory behind immutability and isolation and how it can enable easier parallelism. I have yet to see practical examples of that in Haskell and convincing stats that show a boost in performance compared to more traditional approaches (such as Java+nio or even Scala actors).
My questions still hold regarding Haskell's adequacy in production, e.g. with regards to database, logging or continuous integration, and I'm not the only one: Alex Payne recently expressed the same concerns on SO:
