A short post by Tyler Cowen at Marginal Revolution lays down what I think is the most important element of economics blogging.
People who learn economics through the blogosphere also receive feedback, especially if they sample dialogue across a number of blogs of differing perspectives. The feedback comes from which arguments other people found convincing. Do the points you wanted to hold firm on, or cede, correspond to the evolution of the dialogue? This feedback is not as accurate as Rybka but it’s an ongoing test of your fluid intelligence and your ability to revise your opinion.Not many outsiders understand what a powerful learning mechanism the blogosphere has set in place.
For both the author, readers, and people that comment that blogging experience adds value, not just from the initial post, but from the conversation that takes place following the post.
I know my reasons for blogging are purely selfish. I want people to tell me why I’m wrong about things, and how I can improve my understanding of issues. Furthermore, I like the idea of having a historical record of my opinions – so if similar events happen in the future I can quickly jog my own memory.
