I don't watch American Idol or much television period, save for House, Burn Notice, and whichever Law and Order whatever network it is happens to put on on a given night. Consequently, I miss a few things.
Along those lines, who and what is Simon? Does he matter? What does he say? Are these questions important? Why should we care?
These and many other issues are no doubt things I need to think on, possibly with a glass of wine or two. The popular-culturally-connected may want to enlighten me beforehand.
