  Interview with Greg Dekoenigsberg - Red Hat Community Architect

* What do you think is the biggest misconception about Fedora? *

That it's just a beta for Red Hat Enterprise Linux. It is most assuredly 
not. There are over ten million users of Fedora worldwide. If Fedora 
were "just a beta", I can't imagine that so many people would use it, 
and contribute so proudly to it.
