Last night I met Rainer Erlinger, who writes an ethics column for Germany’s Sueddeutsche Zeitung. He’s a lawyer and a doctor who still practices in both fields. He says his real fun is writing the ethics column for the past five years. We talked about column writing and blogging, and he’s amazed at how popular blogging is in the U.S., compared to Germany. A friend of his is an urban planning student, whose goal is to create public spaces that encourage people to meet one another. That goal ties in nicely with Knight Foundation’s Knight News Challenge, where the goal is to use digital news and information to bring people together in a geographic area. So, I realized there’s another discipline from which we can recruit News Challenge applicants.
