Is there anything easier to do than criticize?
I notice that a lot of newspaper columnists criticize a given politician, athlete, coach, general manager, actor/actress, or director with the greatest of ease. In turn, bloggers criticize the columnists or agree with them. I guess the podcasters then follow up with more criticism.
Because it is easier to criticize than come up with your own thoughts and ideas. Also, if you have a blog, radio/TV show, column, etc., you have to fill space with something. And you can either be original, come up with a top 10 list, or criticize (plagiarize) someone else's work. It's a major part of journalism now. Heck, that's what I've been doing. Shame on me.
