OS X Lion scrolling is reversed, but don't panic, there's an easy fix
Lots of people on Twitter and various social networks are noticing and not liking that the default scrolling direction in OS X Lion is reversed from what it used to be. "Up is down and down is up," as a few people have said. No worries! You can easily fix this by going to your mouse or trackpad preference pane in System Preferences. You'll see a preference called "Scroll Direction" that is set by default to "natural." To change this setting to the old way (which I guess is now called "unnatural") just uncheck the box. Easy peasy.
