That's interesting. I just looked again and I had exactly the same problem for this same site and raised it a couple of years ago as well. The same guy, Ward Cunningham, sent me the text of the page but was otherwise not receptive to my plaint (but wasn't rude). I guess if enough people (more than two anyway) start complaining maybe he'll listen.
I do share your frustration with clever shit over basic usability. Flipside is, I guess, Cunningham isn't your average guy. But I think lesser mortals are still allowed to disagree.
Anyway, thanks for actually complaining instead of just moaning and doing nothing like so many others on the web.
