Kazaa: Can’t stop P2P

What does it say about me if I confess I’ve never used Kazaa–too nervous about worms and viruses?
My son the teenager has a computer loaded with music he’s used Kazaa to pull off the net, and I have a great time hanging out with him listening to to Squarepusher, Infected Mushroom, and remixes of 90’s house.
Neverthless, Kazaa says that users have downloaded more than 230 million copies of their file-sharing program.
According to the San Jose Merc, “In just over a year, the software used to download free music over the Internet has surpassed all other applications distributed through CNet’s Download.com site — including ICQ, the predecessor to AOL’s Instant Messenger, and WinZip, the software utility used to open compressed files.”
