I don't think most newspaper people resent bloggers. Many of us enjoy reading blogs (my personal favorites: The Starting Five, Deadspin, The Big Lead, The Consumerist, Joe Posnaski's blog, TrueHoop, Hoops Hype). I respect what they do, but I can also understand why some journalists are bothered by certain blogs/bloggers. Some blogs/bloggers put out unsubstantiated information and pass it along as fact, forcing more responsible entities to waste precious time following their bad reporting. And there are definitely times when I feel blogs -- even some of my favorites -- cross the line and don't hold their readers to a higher standard.
Neverthless, the benefits of blogs far outweight the negatives. They have forced journalists to get a better sense of what readers want, sharpen their skills, be more creative and hold ourselves accountable. It's egotistical for a journalist to consider themselves the final authority on writing and reporting. We're not. It would be dangerous for me to believe what I do is more important than Michael Tillery at The Starting Five. That's how you wind up being mediocre.
