I've found a couple of links to "Startup Success 2006," a video of a Silicon Valley panel discussing what it takes to be a successful startup today. Panelists include:
Lauren Elliott, Founder, Personal News Network
Reid Hoffman, Co-Founder and CEO, LinkedIn
Joe Kraus, Co-Founder and CEO, JotSpot
Daniel Mattes, Co-Founder and CTO, Jajah
Alex Welch, Co-Founder and CEO, Photobucket
It's worth the 90 minutes it takes to watch. Here's the link: Startup Success 2006
For those of us who are time-deprived, Dharmesh Shah, (whose blog I really like: onstartups.com) has done a great summary: Dharmesh Shah.
