User Group Gathering (Revisit)

We (Hong Kong .NET User Group) organize the first member gathering last week, and our Arts director edited and uploaded the photos to our portal site yesterday:

It's really nice to gather our members in Microsoft office on that day, and we invited a software architect and a Microsoft Certified Trainer to present 2 x technical sessions as well. I believe there's no dead air on that day, but why do Andy (The guy in white polo shirt) always playing his mobile phone even he sit so near to the stage? oh wait... is it because I am speaking on the stage? :P
