Re: should celebrating your opponent's errors be an unsportsmanlike conduct offence?
I don't think the rulebook needs to be rewritten only because of Ivanovic. Sure, it's an eyesore, but you can't just erase such childlike behavior. It requires years of maturing. Or, she has to consciously suppress the urge to celebrate her opponent's errors, which would end dramatically like Seles at Wimbledon '92.
Also, you would have to draw the line somewhere. When is it inappropriate to celebrate? What about very long rallies that end in an error? Or very important points that end in an error?
