First of all, presenters and judges of all shows should be listed in chronological order beginning with the first people assocated with the show to who is on it now.  That only makes sense.  It looks very confusing to the reader how it stands right now.  Another point is the years should be listed fully.  For example as it stands now 2009-11, some people might not understand what that 11 stands for, not only does it not make sense but it makes the rest of the information look very sloppy to the eye.
