Patrick Goldstein, one of our columnists, has started a a new blog, This Big Picture. In one of his posts, I think he gives a great overview of why so many newspapers are starting blogs.

But in journalism, it’s time for a change–big change. As you might have heard, this newspaper, along with virtually every other paper in the country, is under siege. Our whole business model is in free fall–circulation is dropping, profits are down and lots of talented people are losing their jobs. We can moan and groan about it or we can try something new.

That’s the idea behind launching the Big Picture blog. As much as I’ve loved writing a once-a-week column, the world of entertainment and pop culture is moving so fast that it’s become impossible to keep up with all the action without weighing in more often than once a week. Over the past few years, I’ve found myself addicted to reading blogs. The best ones offer a wonderfully brainy, personal and irreverent way of seeing the world. You’ll see the paper now has 40-plus blogs, with more being launched all the time.

My guess is that someday soon our blogs will be the backbone of the paper. Journalists have discovered, to our chagrin, that information is everywhere these days. But readers still crave informed analysis and lively writing, which is something we can focus on as newspapers make the transition from mass circulation entities to niche-oriented publications. So while I’ve got lots to learn about the blogging life–and will surely stumble many times along the way–I’m eager to be a part of that new conversation.
