Inside Facebook's World Headquarters

> Whiteboards were everywhere. So were blackboards, as well as artwork and slogans applied directly onto walls.

I'm a little surprised at the blackboards. When we were expanding once at my employer and I was moving to the new office suite I asked if I could have a blackboard instead of a whiteboard in my new office, and the head of engineering said no. His reason was that chalk dust gets into computers and is not good for them.

I wonder if he was wrong, or if Facebook has more tolerance for trashing computers than we had.
