Some readers may recall one of my predictions for 2012 was the end of this column. It’s time for me to start explaining what that’s all about. Next month will mark 25 years of my doing some version of this column either in print or online. It’s not a record (I’m sure John Dvorak has that) but it is a milestone that I’ve been for some time determined to reach. But having achieved 25 years of continuous service, what then? Well there is no gold watch. In fact my transition is, if anything, forced by the declining economics of the web. Facebook has much the same problem.
