In thinking about this...Am wondering if this is not an unexpected malfunction. If this works via mobile and not, say, via desktop web browser, doesn't that depict the whole point of the site/initiative: That not everyone can equally experience the internet, or has equal access to the internet? If I'm right, this is a clever albeit very, very subtle method to help folks feel what "lack of internet" is like. Welcome to the internet of the third world?

Facebook did not exist yet in 1993 (Facebook.com itself was registered in 1997)
I didn't get it when I first saw this post. Now that I'm checking it on a computer, I'm getting a blank page. Works like a charm on my iPhone. Same Wi-Fi, same DNS.
