Interesting how the article mentions it would seem intuitive to someone new to the game as well. Just hit where there's less defense and more area to cover, the outfield.
Sure, more area to cover but also a lot more time to get there. It's less trying to hit to the outfield, but rather hit homeruns. The problem is that it's easier said than done, and the old philosophy (look at Ichiro for example), was higher average and putting the ball in play was preferable to loading up and trying to hit a homerun. Now strikeouts and homeruns are way up, but batting averages are down.
