Most of the information on this topic is crap." "What do you mean by that?" Crade demanded. We all looked at him, because in an instant he had become markedly defensive. Sammann raised his eyes from the screen of the jeejah and gazed interestedly at Crade. He let a few moments go by, then responded in a calm and matter-of-fact tone: "Anyone can post information on any topic. The vast majority of what's on the Reticulum is, therefore, crap. It has to be filtered. The filtering systems are ancient. My people have been improving them, and their interfaces, since the time of the Reconstitution. They are to us what the Mynster is to Fraa Erasmas and his kind. When I look at a given topic I don't just see information about that topic. I see meta-information that tells me what the filtering systems learned when they were conducting the search. If I look up analemma, the filtering system tells me that only a few sources have provided information about this and that they are mostly of high repute-they are avout. If I look up the name of a popular music star who just broke up with her boyfriend," Sammann continued, nodding at a tearful female on the speely, "the filtering system tells me that a vast amount of data has been posted on this topic quite recently, mostly of very low repute. When I look up the excavation of the Temple of Orithena on the Island of Ecba, the filtering system informs me that people of very high and very low repute have been posting on this topic, slowly but steadily, for seven centuries." Sammann's explanation had failed if its purpose had been to settle Crade down. "What's an example of a person of high repute? Some fraa sitting in a concent?" "Yes," Sammann said. "And what would a low-repute source be?" "A conspiracy theorist. Or anyone who makes a lot of long rambling posts that are only read by like-minded sorts.
