Viewing the existing site in a desktop browser, I get to see the description of Haskell, and a bunch of useful links about learning it, downloading an implementation, using it, and participating in the community. Recent news items and upcoming events are also visible, as is the search field.
This new design lacks pretty much all of that. Instead of useful content, links and functionality, all I'm seeing are large areas of purple and white, and an extremely blurry photo, along with content of very limited value.
I just can't see this new design being beneficial in any way. It makes it much harder to get useful information about Haskell, which seems very contradictory to what a website like this should be doing.
