Haskell does make a great semi-formal language with which to communicate functional programming ideas, even if you have no plans to ever use an implementation of it. Mainstream languages are beginning to borrow more and more ideas from it (albeit often with significantly more verbose syntax). Much of the research literature in functional programming also uses Haskell syntax, so IMHO it is worth any developer learning.
