I just love this photo I snapped at the Inbound Marketing Summit in San Francisco this week #IMS09

Panel was called Discovering the Power of Your Community and included these executives from very successful companies:
Markus Nelson, Co-founder, UserVoice
Joseph Kleinschmidt, CTO, Leverage Software
John Kembel, CEO, HiveLive
Ross Mayfield, Co-founder and President, Socialtext
I guess if you're looking for VC funding in Silicon Valley this is what you should wear.
