made aernet, if you statement in the public sphere, he would get a few letters written in greenbank and those people always used green and and often wrote in capital letters, and was a terrible things in a letter. you would crumple it up and throw it in the bin. those people now have twitter. they can have as many accounts as you would like and can save their repetitive things. it's almost as if twitter was the normal place to go to violate norms. presidents can participate in this process. what can we do you ask? ourink what we can do in nonvirtual, academic communities, is encourage amongst our students and faculty the correct mode of discourse in the civilized, open society which is that there should not be talk -- topics that are but there are modes of discourse off-limits. i will give a little bit of an example here, civil debate on all the issues including and perhaps particularly the most sensitive issues. we will not get them on twitter. i doubt we would get it on facebook, but we can get it at stanford. ms. rice: with that, i think ni joe for assimilating this and thank you all
