No disrespect intended at all Robert, but if dogs get 7 years of credit for every year they stick around, what should internet trends, fads, and norms get? 
4 years is a lot of time for consumer behavior to be influenced by certain norms on the web. I think you'd see very different results today.
I love this stuff because it is a reminder of the pace of the culture we live in. I find it really interesting...
In August 2008, Facebook had 100 million users, today they have 1.15 BILLION. Do you remember the first time you "liked" something on the web? Feels like it has always been a part of our shared experience since the beginning of the world wide web, right? The term is pervasive in our culture and we've been conditioned to believe that our "like" gives value to others. This may shock you... The infamous "Like" button didn't come on the scene until Feb. 2009! A lot can change in just 4 short years...
Instagram, Foursquare, G+, and Pinterest didn't yet exist when President Obama was elected in 2008. But the biggest game-changer of all, the most prized possession of millennials and the bane of most car salesman's existence was just barely birthed in 2008. Today, you turn around and drive home if you forget it, the aforementioned millennial would choose it as a marker of personal freedom above a car, and its meteoric rise in our culture is without parallel. It is hard to imagine that in 2008 there were just 2 on the market...the iPhone was launched in June 2007 and the first consumer Android device, the HTC Dream, didn't go on sale until late October 2008!
LAST THOUGHT: I joined the DealerRefresh Forums in April of 2009, just 2 months after the Like button debuted! This post is incomplete without a HUGE nod to Jeff and Alex for their ability to see into the future and create this thriving community. It's pretty incredible when you think about it.
