Yes. C is the language of operating systems and browsers and low-level
system utilities -- not, by and large, the backbone of today's web
applications. Projects written in C/C++ tend to be ignored in favor of
those written in Java (Hypertable versus HBase, for example). There
are exceptions, but there are fewer of them over time. Java's spot in
the middle tier has overflowed into the bottom tier, as performance
and community size have increased.
Moreover, C libraries are seldom cross-platform (leading to wasteful
fiddling and endless frustration), and they are painful to interface
with due to the requirement for detailed type annotations, which are
easy to get wrong. JVM is cross-platform, and contains sufficient
typing information to permit one to write something like, "import
foreign jvm java.list.Collection", and have typed access to the whole
class and all of its methods.

Out of curiosity, why do you think that porting Haskell to the JVM
would make such a large difference? Haskell can already interface
with C libraries; are there really so many commercially vital
libraries that are JVM-only?
Cheers,

It's a bit of a chicken and egg thing. I'd switch to Haskell in a
commercial setting if there were more good libraries, yet the act
of switching would lead to the production of more good libraries.
The latter, though, is cost-prohibitive, given all the components
that would need to be developed. A few years from now, or post
Haskell-on-JVM, I might be singing a different tune.
I do greatly admire the work you and your company have done for
Haskell.
What has the Industrial Haskell group done so far? I haven't seen
any announcements. The work I'd be most interested in helping co-
sponsor is Haskell on JVM (biggest bang for the buck).

* Haskell interfaces to Twitter, Facebook, MySpace, Google, etc.
This one is fine:
twitter
hs-twitter library: Haskell binding to the Twitter API
del.icio.us
delicious library: Accessing the del.icio.us APIs from
Haskell (v2)
friendfeed
ffeed library and programs: Haskell binding to the FriendFeed
API
LiveJournal
feed2lj program: Cross-post any RSS/Atom feed to LiveJournal
flickr
flickr library and programs: Haskell binding to the Flickr API
amazon
hS3 library and program: Interface to Amazon's Simple Storage
Service (S3)
mediawiki
mediawiki library and programs: Interfacing with the
MediaWiki API
google pubsub
pubsub library and programs: A library for Google/SixApart
pubsub hub interaction
Speaking of REST,
RESTng library: A framework for writing RESTful applications.
And auth:
WindowsLive
windowslive library and program: Implements Windows Live Web
Authentication and Delegated Authentication
OpenID
openid library: An implementation of the OpenID-2.0 spec.
OAuth
hoauth library and program: A Haskell implementation of OAuth
1.0a protocol.
We've obviously not all there yet, but we have a way to get there --
write and improve code on Hackage. Galois is doing its part (we've
released dozens of web packages), but the other commercial users
need to
help out too.
Join the Industrial Haskell Group and fund open source work. Or,
if you
can, release some of the non-IP-encumbered things you work on!
