It's foolish to think these entities don't have their own agendas, and so the convenience of the Information Age is offset by how much more discerning the receiver of the information must be. If not, then the Information Age turns out to be an elaborately hyped and supported game of Telephone, that kids' game in which you tell your friend a bit of silly news—"My dog threw up on my mom's favorite dress"—and they whisper what theyheard to another and they to another until the last recipient announces, "The OC Weekly murders Arabs."
Your mother was right. When receiving any information, it's always important to consider the source. Or, better yet, to go to the source itself. In these times, we can't afford casual readers.
