Yesterday I spent the day at TechCrunch's 'Real Time Crunch-up'. This despite having no idea what a 'Crunch-up' actually is. The important thing is that Erick had asked me to help moderate his panel about marketing within 'real-time streams' , which is a subject close to my heart. So close in fact, that had he asked me to help moderate a panel about child rape and it's place in the public school system I couldn't have been keener to weigh in. I'll get back to my own contribution in a moment, but first, as a courtesy to my paymasters, I should probably relate a few of my 'key learnings' from the event. 1) There is such a thing as a 'key learning', a phrase which I heard at least three times during the day, and which I gather is what an 'opinion' becomes when spoken by an idiot.
