I think that's true, certainly to a degree: Perhaps the subject matter is a bit more detailed (or unusual) but at a higher level it's not much different.
I can't tell you how many hours I've wasted in the evenings watching things on Youtube that are probably a waste of time but I find fascinating nevertheless. PilotsTubeHD is a fun channel for watching pilots doing their thing. I also can't stop watching bosnianbill's endless lock picking videos. Maybe there's something wrong with me. :)
