Sure, you can show it to your local Genius -- you're still within the one-year warranty on that machine, right? Otherwise, the people who can interpret them hang out on the apple.com forums. If it's something decipherable -- like a USB error or something from a particular application -- you should recognize its name in the log, but there's no harm in sending it off to AppleCare either. ~Linda
