I can tell you what me and my colleagues would be interested in (though none
of us are actually going). We code a lot of math. You may call it scientific
computing. Haskell seems like a natural fit for the task.

In particular we are interested in:
1) the type system
2) concurrency (can these be set to run on a large system)
3) simple relation between what equations we write on paper, and what
equations we write in haskell.

I'm still a n00b to Haskell. For us languages like matlab, maple, etc. do
not fit the job very well and run too slowly. C/C++ is usually what i use
but it can be a pain. Python, etc... well its good for the glue i suppose.
Haskell might fit that niche.
