someone from W3W appeared at The Fully Charged Show Live, on a panel talking about disrupting technologies.

if you didn't think too much about what she said, and particularly hadn't read this blog post and the comments, you might think W3W was the best invention ever for navigation. But if you know about the alternatives and and understand that W3W is proprietary, then you'll find yourself thinking "but..." every time the speaker asserts something great about w3w.
