Not all customers are created equal. Last month Dean Detton became Zoho's one millionth user and a press-release darling. Tonight you can celebrate the milestone with the Zoho team, Detton, and a band of Office 2.0 revelers at Vitrine in San Francisco at 6 p.m. For a bit of digital underground, SF New Tech is partnering with their buddies from the SanFran Music Tech Summit to transform Mighty into the demo depot it so longs to be. Rock out to the geek beat from 6:30 to 11 p.m. Tonight the Churchill Club is hosting "A Second Strike of Light-Ning?" with Marc Andreessen. To hear the man behind Netscape (and Facebook's newest board member) in conversation with Portfolio's Kevin Maney head to Cabana in Palo Alto at 6 p.m.(Photo by b_d_solis)
