LinuxWorld is no longer as cool or fun as it once was, but I tend to find it worth it just to get the latest Debian t-shirt. I often donate to the EFF as well when I'm there, and sometimes there is something else neat to see on the floor. It is currently possible to register for a free exhibits pass. They apparently also have www.linuxworldexpo.com/live/12/ehall//SN460564">community days, which you can register for (also free!). I registered for the Ubuntu one, hopefully I'll be able to make at least part of that. Anyways, if you're going to go, drop me a line, and maybe we can meet up at the show.
