Pavlov DogTube

I saw a commentator, ages ago, talking about this. He said that the numbers-tally is the addictive aspect of the whole YouTube thing. It's how YouTubers get their 'fix' and feel validated. I think there's something in this. It's a 'reward' that doesn't cost Google anything. Participating in YouTube has, at times, made me feel like a pigeon in a behavioural experiment - Google switches-on the light, and we all press that button =p Excuse me, I'm inexpicably salivating. Oops! It's that bell again!
