It can, and is used. See the industry page,
they're the big players, there's numerous small groups that have maybe a
few in house Haskell tools.

I suspect the best place to advertise is still haskell-cafe at haskell.org.
Most jobs seems to be sent here, and its also cheap :-) You have access
to a few thousand competent Haskell people directly.

gtk2hs is probably the most 'industrial' UI lib.

Well, best to find out. In practice i've not found GC to be an issue.
Premature optimisation and all that.
