The Times has an excellent example of a columnist and blogger thinking out loud.
On the blog he started last week (gladwell.typepad.com), Mr. Gladwell noted that the blogosphere has, for some mysterious reason, picked up on the debate [on Canada’s health insurance system]. “But wait!” he wrote. “That was six years ago! I’ve now changed my mind. I now agree with virtually everything Adam said and disagree with virtually everything I said. In fact, I shudder when I read what I said back then.”
Much like a conversing with friends, blogging is an exercise in speaking, receiving feedback, and evolving ones thoughts and opinions. Collecting history such as this may help fight notions that “Googling” someone to find out about their past really tells us something about who they are today.
