And now for something completely different.
It has been commonly said that all web applications are glorified guest books. While we all know this not to be true, I think that this has evolved into a more recent conjecture that most web applications are glorified blogs.
Now, it takes between five and thirty minutes to set up a blog using one of the preexisting blog software packages out there. Most of them are pretty straight forward as well. So, if I said that one of the most complicated web apps I've seen in a long time is a blog, you'd likely laugh in my face.
This site violates pretty much every rule of web UI design. The content on the site is not information as much as it is a bunch of people arguing about current events and the righteousness of public opinion. It's a blargument(TM). Very strange.
I'm a bit biased, as it was developed here at the $DAYJOB. With respect to the technical side, there were a few intensely challenging aspects to the project. As for the DHTML involved, to quote some old dude, "something wicked this way comes."
Take a look, if you can survive the outright attack on the senses, it is clever and punchy on both the concept level and technical level.
