Worth pointing out: this is, in no way, done by a single media organization. This is a collaborative effort of ~107 news organizations from all over the world, and you can be sure that behind each of them there's a small dedicated tech team that worked tirelessly on making this thing look pretty.
Because this is such a huge collaborative effort involving over 300 journalists from god knows how many countries, we barely managed to set an embargo until 8 PM (CEST). An hour before that, there were literally less than 10 tweets using #panamapapers. Now, there's over half a million. And it's been just seven hours since I have started the tweet wall in our office!
From this point on, I believe that every media organization is going to focus on its own region, although I cannot guarantee that. After all, my job was to make the website look pretty. I had the honor of reading some of the stories before anyone else while I was preparing them for the website (and I will have the same honor again in ~5-6 hours), but that's about it.
