If you have counterexamples, then perhaps you can name them. I'm  
looking for Java shops with 5+ developers and code bases of > 100k  
converting over to Haskell. I don't know _any such shop_ that has  
switched to Haskell, and I doubt any exist, but I'd be delighted to  
learn I'm wrong.

Let me ask you this question: how long would it take you to get an  
HTML/CSS, W3 compliant browser in Haskell? Or how about a peer-to-peer  
networking system with seamless scaling and automatic failover? How  
about a scalable BigTable implementation? In Java, the answer to these  
questions -- and just about any others you can think of -- is "a few  
minutes", because the code has already been written.

Libraries are _everything_. In many cases, they can increase your  
effective budget by 10x or even 100x. That means instead of having  
$100k for a project, you suddenly have $1 - 10 million worth of  
resources at your disposal.
