Should American Idol Keep the 4 Judges?

According to this article, http://tv.yahoo.com/blog/tvguidecom-readers-get-rid-of-kara--292, 60% of you think Kara DioGuardi should leave Idol.

Here is what I think based on the article: Because Simon's contract ends after 2010's season and has stated that he is likely to leave, then we should keep the 4-judge lineup as it is for next season ONLY. Once/if Simon leaves, American Idol should reasess the 3 judges, Randy, Paula, and Kara, and decide who among them should stay but still ONLY keep it a 3-judge lineup. There is just not enough time for any of them to talk with the 4 judges. I personally think they should only keep 1 of 3 remaining judges; and I'm leaning towards Randy or Paula.
