Well, there are always people in the audience who ALWAYS want some sort of information to take with them, (The Gatherer), there are ALWAYS people who would like a time to socialize and get to know each other, (The Socializer), and finally, there are ALWAYS people who try to accomplish a lot during the time they have, (staying on topic, also know as the Time-Watcher). These are the key groups to look out for in an audience, and you could make sure that you have everything prepared for PURE satisfaction. The groups were from a book by Cyndi Thero. I just made up my own names for them.
