Change for the sake of change isn't always a good idea. When Pepsi first "updated" their logo a few years ago, I did this mockandscoff of it and posted it to my DeviantArt account. My daughter was going to art school in San Francisco at the time, and PepsiCo had plastered the logo all over downtown buildings. Four of them stacked one above the other, 100 feet square, all over downtown. Finally she had enough.
"MOOO-OOOM!" she cried into the phone. All I see is huge bellies all over the city! You've ruined it for me!!"
