Americans don't go to news stands for Linux information? But it wouldn't surprise me if the percentage of Linux users in the US wasn't the top in the world either. We still have Linus now and Redhat though. That has to be worth something right? Years ago I used to have a subscription to the Linux Journal, shipped to my US address of course. Just figured I'd throw that out there. Now if I want Linux info I hit up my PC and use man, or maybe Google, depending on what I'm looking for, aptitude search is pretty rocking too.
