Wow. Jason Calacanis is leaving the blogosphere. I relate to how he feels; this stuff takes a lot of time and thought and you have to have the nerves of a stand-up comedian to keep doing it everyday. His blog was a good read and he will be missed.
I bet Jason will be back though in some manner or other and soon. After all, he is the Brett Favre of blogging.
There is now so much user-generated content and so much inventory. The big ad networks drive all of the sales and the power has shifted to the advertiser NOT the media itself. This is a unique phenomenon. Social networking inventory doesn’t respond very well. Jason Calacanis is correct. The industry should look at this inventory as a mini front door to drive traffic to inventory that responds well and that carries a higher and more respected CPM from advertisers.
