Why did I write the site in Haskell? First, I was ask to fix the site
that was selling products they didn't have in stock. Once I looked at
the source code, 25000 lines of ASP, I reckoned it would be easier to
rewrite it in a real language. Second, I couldn't find any commercial
sites written in Haskell, and I thought this would be a good chance.

The new site has considerably more functionality and is a little over
4200 lines of Haskell. The original site could only display and sell
products, without any consideration of whether any were currently in
stock. Furthermore, the site content could only be maintained by an
expert user. See the old site at

.

If anyone wants to have a play with the CMS, email me privately, and
I'll give you a nobody login.
