I’ve been a Linux user for a long time, eight years in fact. Now I’m not trying to toot my horn, I merely am pointing out that I’ve been around long enough to see a lot of changes and a number of flash-in-the-pan distributions come and go. Most of the time the short lived distributions were simply repackaged and re-branded versions of an existing Linux project like Red Hat or whatever and they were pretty easy to pick up. Everything looked and felt like a Red Hat system but this “new” distribution focused on a certain aspect. Mandrake Linux or Linux Mandrake as it might been more commonly called back then, was in fact based on Red Hat but with an experience more focused on KDE and ease of use. Today of course Mandrake is known as Mandriva and you can no longer say that it is simply a repackaged Red Hat (or Fedora) distribution.
Now like I said, I’ve been using Linux as a desktop or server OS since about 1999, probably longer than a lot of people. During that time I pretty much have used Red Hat (or Fedora Core) exclusively and I’ve grown accustomed to it’s inner workings. I don’t have to reference anything to know how to install packages, what packages are called, manage services, edit config files or what have you, it’s all just familiar territory. Much like walking around my house in the dark, there are no surprises anymore.
