definitely increase in no. of iit's will bring down the quality of input to these institutes of international fame.as i myself is an 3yr b.tech elec engg student at iit madras ,i am well aware that the faculty of rec's and other colleges is noway comaparable to iit profs.increase in no of iit's will serve no purpose rather tarnish the fame iit'ians have earned over decades all over the world.
