There are many things about these shows that pique our interest. For me, nothing is more exciting that a Steve Jobs keynote address. I love exploring the show floor and perusing tons of technology. I love geek parties, especially if there is music and dancing. Part of the Expo Experience is the phenomenon of boothbabes.
Different vendors use different approaches populating their expo booth.
At geek shows like Macworld Expo, the folks in the booths are predominantly full time employees at the company. We can expect a lot of product knowledge and interest in us as customers from these dedicated individuals. Then, there are the local models and actors who are hired just for the show. These may be booth flowers who hand out literature with a practiced smile, or they may be well coached in product knowledge and answer the toughest of questions. The highest profile approach is when the presentations amount to entertainment.
