I go to his site for the news that will be on the talk shows--this way I get all the info in about 15 minutes and can avoid talk ready unless I want to hear more insight on the topic.
I'm just a little too busy to listen to Rush and the rest EVERY SINGLE DAY. Before drudge I felt the need to listen to get the latest news from around the nation. But drudge pretty much points me to that news so I can read it on my time.
