Two college-age students are looking at a computer monitor, one standing behind another who is working at the computer.  The one standing asks, "What's that?"  The writer answers, "Today's blog entry."  The conversation continues: "Get out--you have a web log?"  "Yup.  My daily take on what's going on in the world."  The one standing says, "Wow, that's impressive, dude.  I had no idea . . .  Wait, don't you have to have something to say?"  The writer responds, "A common misconception."
