That's all good to criticize someone's article, but back it up. I dont see anything about your experience with blogs NOT ranking well - since most of the posters here say they do. I'd like to see some evidence that they don't rank well at all. Anyone?

I really haven't tried it much at all - but I'd like to see if anyone got bad results?

By the way, your methodology is faulty. A check on Overture for "business world" means nothing. I've seen keywords appear one month and disappear the next.
