Most of the other activity entries I have written about involve major events that attract large numbers of people. But a Worldcon will also have a large number of small events catering to specific tastes. Most of these are in the form of a discussion panel. A small group of experts gets to hold forth on some topic for a while, and then takes questions from the audience. Other events include speeches by the major guests, autograph sessions, and "Kaffeklatsches" - limited attendance events at which an author discusses his or her work with a small group of fans.
The principal Guests of Honor in Chicago were author Ben Bova, artist Bob Eggleton and editor/publisher Jim Baen. I confess to having been too busy to attend any of their speeches, but I know that Eggleton kept himself very busy because I kept seeing him around talking to people and painting.
Other than the main guests, there were over 100 published authors at the convention. Many of them had paid their memberships just like the rest of us, because Worldcon is the place to be. A quick flick through the program book reveals famous names such as Forry Ackerman, David Brin, Lois McMaster Bujold, Orson Scott Card, Joe Haldeman, George R.R. Martin, Larry Niven, Robert Silverberg, Harry Turtledove, Vernor Vinge, Connie Willis, Gene Wolfe and many, many others.
The panel sessions can cover all sorts of topics. Generally a Worldcon program is organized into "streams" to try to ensure, for example, that no two panels on space exploration, or the craft of writing, or costuming, or games are scheduled against each other. But as a member you can pick and choose what you go to. Here is a random selection of topics, which will hopefully illustrate the diversity, and in depth knowledge, that was available:
Writing for children, discoveries made by the Gallileo spacecraft, how to enjoy a convention, copyright and the Internet, commercializing space, the Robin Hood legends, the making of Toy Story 2, designing computer games, developments in longevity, the treatment of gender issues in SF, building your own rocket, nineteenth century fantasy writers, low budget filmmaking, computer viruses and, most fantastic of all, the prospects for a Cubs v White Sox World Series.
And if you were really unlucky you could come and listen to me holding forth of how to review books.
The important point to note here is that I have barely scratched the surface of what went on. I haven't even mentioned the gaming, or the films, or the kids program, or the music and theatre performances. There were 22 separate rooms used for programming, all of which were kept busy for most of the day for five days. The biggest problem I normally have with a Worldcon is deciding which events to go to, because there is so much interesting stuff going on.
