Come on. Linus wouldn't even need to use Linux himself (ok, that would strike me as odd, but anyway), if he didn't want to. The guy is the "father" of Linux (as in "Linux the kernel"), not every piece of GNU software. He can't run just Linux, because in addition to the kernel some software is needed
and no matter which distribution he'd pick up, somebody would pop up and say "heyyyy! now we all know the truth, Linus thinks this distro is the best!!! weewohoo!!!!) -maybe he just likes Fedora, it doesn't state that it's the best or it's what he considers the best. Linus might think Solaris is the best thing around; he might think Coyote Linux is the best thing around, but for daily use he just happens to use Fedora. Or he might have a thousand other reasons not to install Debian, Gentoo, Slackware, ... to all of the computers he uses.

According to a recent interview Linus runs Fedora 7 on most of his boxes.
Yeah. It could be 2501 out of 5000 (that's "most", >50%). Admit it, this is something stupid fans do when they hear their idol has just spit on the wall..
Very probably Bill Gates has installed Windows Vista on most of his computers (maybe 100% if he only had one), and still that doesn't mean Gates thinks *really* that Vista is the best thing on earth. I wouldn't.
I've installed several Microsoft Windows operating sysems on computers I deal with, more than Linuxes. And I do not "necessarily" think Windows is the best OS here. But I guess you would translate it like that.
