On the Daily Show earlier this week, Arianna Huffington tried to convince Jon Stewart that he should put his thoughts into a blog for her news and opinion site, The Huffington Post.

Stewart responded by noting that “when I have thoughts, I put them on the little screen in the living room”.

Huffington then argued that he likely had “more thoughts than what you use on the show”.

To which Jon came back with probably the best reason I’ve heard for performers (or anyone else) NOT blogging.

Why should I give people the dreck?  Shouldn’t I try to focus it and make it as good as I can… because my other thoughts, there’s a reason I haven’t put them on the show.

Huffington was there hawking a “guide to blogging” book which sounds like recycled versions of advice you can find all over the web for far less than fifteen bucks.
