From the streets of Cairo and the Arab Spring, to Occupy Wall Street, from the busy political calendar to the aftermath of the tsunami in Japan, social media was not only sharing the news but driving it.
Being here, it is just impossible to imagine what that was like, when the tsunami hit.
Any time they try to describe the tsunami to us, I am so touched by how high they look in the air, when they explain it with their hands-they go so high.
If I hear about a tsunami that hit Asia, hundreds of people have lost their lives, and you see it and you hear about it, but you still brush your teeth, still have to go on with your day. But let you get information about one person who you're close to or you're intimate with, it has an almost paralyzing effect.
We still carry this old caveman-imprint idea that we're small, nature's big, and it's everything we can manage to hang on and survive. When big geophysical events happen - a huge earthquake, tsunami, or volcanic eruption - we're reminded of that.

What is perhaps more worthy of note than how many tsunami dead we've seen, however, is how many other recent dead we have not seen.
