I’m not a hero and don’t claim to be, but when I was given this talk to do for the SMACC 2013 conference I researched the topic and realised I’d worked with several of them.
The talk was the toughest I’ve ever given, because I cried while giving it, and knew that it wouldn’t just be the large audience in front of me who would know I was a wuss, but that it was being recorded for many others to find out too!

A full transcript of the talk, the slide set, and links to references from the talk can be found here.
