Family Judges ;)

We have been seeing Unnikrishnan, Sujatha and Srinivas in the Airtel Super Singer 2008 show for quite long time and I even felt for other/new judges replacing these three.. it would be better to see what others say even.. but last few episodes we have been seeing Malini Yugendran referring them to "Family Judges".. quite interesting.. also If you had noticed during the quarter finals in the show.. Yugendran and Malini kept on saying "Final Quarter finals".. I donno when was the previous quarter finals took place and even pre quarter finals... is it bcos the show wen to quarter finals & got recall rounds and went back to round robin stage ???
