this could be a good idea, but in order to do that, you have to get multiple things, like what their into, the way they normally act, their hygiene, stuff like that, and you would have to explain all that stuff as well and actually start up a little questionnaire and find out what the majority of geeks are in those category, and others you come up with. Because if you don't, you might only have enough material for about 10 minutes, thus leaving 20 minutes worth of time, which isn't that good. You would also need pics to show these things as well, and make sure the person in the pics are alright with you showing it so that they don't get embraced.
