It's meant to revolutionize forum systems. Do you think it does?? It's a nice JS-based skin, I'll give it that, but I'm not so sure it's as revolutionary and amazing as it claims to be.
Then again, it only takes one unique twist on an existing idea to make something revolutionary. Too much change and people just can't wrap their minds around it because it's too foreign a concept to them.
For example, take blogging. It was around for over a decade before someone said, "Let's create a blog that only lets people type in up to 140 characters per entry!" and suddenly we have Twitter.
