Maybe a series of funny pinball videos would be a good thing to get more people interested. Instructional videos on how to set stuff up and whatnot that is in layman's terms for people that are on the fence or concerned about the baggage of owning one. Maybe I'll ask my cat if he is interested, cat videos seem to be popular on youtube. Same with farts, or videos making fun of celebrities. All the ones I have with 50,000+ views fit into one of those categories. The stupidest shit you can think of gets viewed.
