I'm at eTail in DC and will be posting notes from some of the sessions:
First up,

Tony Hsieh - Zappos.com CEO - from yesterday - they're slowly moving into other areas, figuring out the model.
They didn't start out day 1 with FedEx overnight shipping for orders and returns, they gradually got there, putting marketing funds into it.
Ten thoughts:
#1 Ecommerce business is built on repeat customers
#2 Word of mouth really works online
#3 Don't compete on price - $10 off customers not loyal
#4 Make sure inventory is 100% accurate
#5 Centrally locate your distribution - KY is good
#6 Customer service is an investment
#7 Start Small. Stay focused.
#8 Don't be secretive, don't worry about competitors
#9 You need to actively manage your company culture
#10 Be wary of so called experts
