Does that really matter?  I tend to judge technology based on its
merits for my work, not on who uses it.  The fact that Google uses
Python didn't impact my decision to start using it, and it also didn't
impact my decision to start using Haskell.

Those, of course, are pretty good questions.

Take a look at Hackage.  There are quite a few other Haskell web
frameworks as well: everything from the low-level FastCGI to
higher-level HSP and WASH.

In what respect?  The fact that something uses
ByteString.Lazy.hGetContents doesn't imply a problem to me.  It's a
useful function.  It can be used properly, or not, just as while or
read() in C can be.

It's not evil incarnate like sprintf() or anything :-)
