Google has made a subtle addition to Youtube. Now users have the option of hearing an audio preview of their comment before posting it . The audio preview feature, apparently, has nary a practical purpose to serve, but the possibility of some people puffing up with vanity after hearing their insightful comments can not be ruled out. The origins of the useless feature can be traced back to a XKCD cartoon by Randall Munroe . Hopefully the audio preview feature will stir the conscience of spammers and make them reach for the backspace key.
