This should not be the basis for your evaluation of the program. Let the quality of the program and what the audience gets out of it be your most important guidelines. The amount of people you get at the event is more a function of the relevance of the topics and your publicity than whether a program is quality work. The size of the audience who is really interested is the product and quality of the program. A common fallacy is to let the amount of money you have to spend on a program limit the scope of your program and your organization's creativity.
Most programs cost little or no money to present.
In addition, fellow students are also excellent sources of free entertainment and knowledge rarely used by campus programmers. Take, for example, the programmer who decides that because a dance went well, to have one every week. After a while, interest will probably decrease because people get tired of the same old thing. In addition, there probably are other students who don't particularly like dancing or social programs and who would rather have academic, cultural, special interest, athletic programs, or a combination of the above. Since all students' fees support hall governments and their programs, a variety of programming events would best suit the needs of all the residents of a hall.
