I was just watching the first episode of Buzzlogic Vino Diaries, a pretty good vidcast where people get together in a wine bar to talk about social media. Just my speed on both counts!
Here, Buzzlogic‘s Valerie Combs talks with Bill Tancer of Hitwise about several intriguing online-media topics — over a fine glass of tempranillo. (Oh, I’m sooooo missing Barcelona again…)
Toward the end, Tancer makes an interesting observation:
“We’ve been tracking social networks as a category — and at the same time I’ve been trying to explain why the adult category has been on a steady decline. Two years ago, business to adult sites comprised about 16% of all internet visits here in the US. As of last week, that’s dropped to about 10% — so quite a steep decline.
“One day, one of my analysts decided to juxtapose those two charts, and put them together on one chart. …We did an analysis and found there’s a perfect negative correlation.
“So we then decided to dive into the demographics of visitors to these porn sites. What we found is that the 18-24-year-olds are disappearing from the adult traffic. And yet 18-24-year olds have been increasing in social networks. So we don’t have a lot of evidence, but we think there is a tradeoff happening.”
I’m not kidding, watch it for yourself. Enjoy!
(Thanks to Jeremiah Owyang for recommending this vidcast, via Twitter.)

I believe there is a direct correlation between the two, I do not feel like getting into great detail about it but I hope you get my meaning.
