One example of this that I was just randomly reading were these pages on AskMen:
Top 10: Ways Men Have Brainwashed Women - AskMen

(Not trying to start a man vs woman debate here, btw :rolleyes
I believe they create content like this on purpose in order to maximize advertisement pageviews. This could be very important if they sell ads based on pay per view instead of pay per click.
Anyways, I've never really noticed small websites run by solo entrepreneurs to split up content like this... even though doing so makes a lot of sense from a financial perspective.
Maybe us website creators should start producing content that fits this method? After all, if all the big boys do it (I've noticed it on dozens of big websites), then surely it must work well?
