For those who haven't witnessed this: pg stands there for an entire day (maybe longer now), watching every pitch, slicing and dicing like a samurai. It's super rapid-fire, and with one or two pieces of advice each presentation doubles in effectiveness.
I'll still talk about pitches individually with startups at office hours.
For example, for Pebble you said, "put this joke in there: 'I bet you guys really want to check your phones right now but you can't because it would be rude... if you had one of these babies on your wrist you'd be able to see those precious emails'".
OK maybe not the most world-changing example but there were 100 more of those.
I'm sure Sam will be excellent at this too.
