Haskell web applications

What do you guys think about using Haskell for web applications? I've Googled around a bit and it's definitely doable.  Wondering if anyone has experience with using some of the frameworks, or doing it from scratch.

The main reason I would not use another language instead is because I enjoy programming in Haskell.

Two modern frameworks that are there are Yesod (jewish crap) and Snap (inscrutable crap), and also some ancient crap like Happs that doesn't even compile anymore.
