I'm not a soccer fan, but if I were, I'd be spending a lot of time in the next few weeks at Marca.com's wonderful World Cup Calendar.
Come to think of it, I've already spent a fair amount of time playing with that calendar anyway, just because it's so cool. The elegant design, clarity of presentation, and usability are worthy of Edward Tufte. It's one of the best applications of Web 2.0 technology I've seen.
Check it out. See how many seconds it takes you to determine when and where Germany is playing Australia, and what other matches are scheduled for that day. See how long it takes you to stop playing with it.
