We all know that the interoperability situation on the Web has been abysmal. Web developers everywhere are vocally voicing their complaints of wasted time and money due to browser differences. Standards bodies that are meant to solve the interoperability problem become battle grounds of special interests, or create ivoryish spec-monsters that end up fragmenting the web even more.

(For the purpose of this exercise let's define the top 4 browsers as IE, Firefox, Safari/WebKit and Opera – latest available final versions).
The winner gets fame and fortune. (Well, I think I can afford a reward of ISK1000 these days if anyone is interested – certainly our friends in Iceland really need someone wanting to buy their money.. :p So the grand price is a souvenir 1000 krónar bill from Jon's country of origin.)
Ladies and gentlemen, post your answers in the comments.
