The original wiki was a wonderful community, alive in that ineffable way that very few online communities are, totally free and public. I wrote a blog post [0] about how strongly it influenced me as a person and the gratitude I feel for it. Ward Cunningham is a respected and intelligent software designer who works on open projects for the public good. The immediate cynicism and dismissal I've seen of his new project…
If you see a car with a small knob for a steering wheel, you'll find that it is more difficult to use. And even though the engine of the car might be a radical improvement, this still doesn't mean that it can be used, mainly due to the pesky knob instead of a steering wheel. Obviously, after a while of using a knob to steer, you can get used to it, but that initial lack of usability means that many people decide that it's not worth the trouble.
Same with the website. You go to a website to use it. Sure, the idea behind the website may be wonderful and innovative, but if the access to it is unusable, then the innovation behind it all is for naught. When implemented well, the innovation is both shown in the explanation of it, and in the interface itself.
Everybody is dismissing it after 20 seconds because it doesn't work. The idea may be good, but the implementation is what is being shown to public. If it were the idea that were being shared, then it would be a link to, for example, a blog post or source code.
Finally, the reason that we're not trying to "learn something about how it works" is because it doesn't work, at least not yet. Which is why we are complaining.
