Read random messages from users all over the world. Worried that they'll be "I can typez message lol omg wtf"? Don't be. A voting system ensures that you only get the cream of the crop. Or at the very least, the cream of the crap.
Share your own genius bon mots and see how other randogram users vote on them. The more positive votes your randograms get, the more people will see them.
Like twitter, but good.
