I think this talk by Eric Meyer is really interesting and worth watching. Be warned, he does discuss his daughter Rebecca’s death of brain cancer (not in detail), so maybe you don’t want to watch this one at work.

Aside from the crushingly sad part, he has some really interesting stuff to say about how the way we build the tools we do (social media like twitter, facebook, linkedin, for example) reflects our values and how that will shape the next generation’s view of what’s normal on the internet. Like he says in the talk, “Show me what you build, and I will tell you who you are.”
