Mandriva used to be called Mandrake as has been around almost as long as Slackware. Unlike the others mentioned here so far, it comes in two guises. A free, open-source version and a commercial version. The commercial version is aimed at newcomers to Linux and contains very good documentation to help you in your first steps. The free version still has a good following, and plenty of ways of learning your way round.

FreeBSD is an operating system based on BSD with a focus on stability. While not based on the Linux kernel I feel it deserves a mention here due to it's similarity to Linux and it's overall popularity. Similar to Slackware Linux it is considered very stable and perfect for a *NIX based server. It doesn’t have the gadgets, fancy desktops or bells and whistles of many of the Linux distributions, which makes it ideal for server applications.

Mint is a cool name, for a cool distribution. It shares the Ubuntu heritage as it’s based on the Ubuntu kernel, but has gone in a slightly different direction. It is all about the desktop and user experience, while making the core as stable as possible. The programmers interact a lot with their followers and incorporate suggestions and ideas into their releases. This is another good distro for new Linux users.

There are many other “flavours” of Linux to choose from, all having varying degrees of presence on the internet for you to explore. With the exception of the Mandriva commercial version, all a free and open-source and update often. Linux is slowly gaining ground as it becomes more reliable, interoperable and user friendly.
