[BM] We don't really know the significance of the Madrid attacks yet, which makes them at present equivalent to the earthquake in Bam. But the significance and symbolism of the 11 Sept attacks were immediately obvious and pretty much unignorable. And arguably what happens in America (at least in some contexts) is more important in terms of international repercussions than what happens here, so the perception is not entirely arbitrary. [ZK] If you're interested in the reaction to Sep 11th, you can see it breaking here. CdM and I were midway through a debate on insurance when Néa was the first person to react, ahead of PaulWay hearing the news. What's really interesting in retrospect is how Drewsxpa provides future MC historians with an aside on the event for context - but of course, the date and the event is now burned on everyone's memory, and we need no such thing.
What you might need context for, on the other hand, is the "yipee" comment on 13 September by "Iain Duncan-Hague". You may recall that a man with a similar name was elected Conservative leader on that date. You don't? Oh, well, hard to blame you.
