That made me reflect on one of the main difficulties of explaining GNU/Linux based operating systems: We (Free software advocates) haven't been able to properly explain that "Linux" is not an operating system, It is the kernel that drives many operating systems, most based on the GNU operating system.
When people say "Linux has many versions" it shows that even people that use one of them don't fully understand that they are talking about many different operating systems. Some more experimental, some more free (as in freedom), some more stable, some more mass market appealing.
- SuSE falls in the later categories, stable and mass market appealing as it includes many proprietary extensions
- Debian is more experimental and more free (as in freedom)
- Mint is in between both.
- gNewSense is mean to be totally free or proprietary extensions.
"Development teams" for the different operating systems are mainly responsible for the packaging and polishing the configuration. That's why the packaging and configuration tools tend to be different. But for the most part they all follow the same standards and moving from one to the other is not a difficult task.
If you are new to Free software, just try a few of them. Stick to one you like. After a while, you will be able to do things in any of them with little difficulty.
If you are a seasoned Free software user, I ask that, when speaking to other people, you to use the name of the operating system (Distribution) you are using and maybe "which is a GNU/linux based operating system".
This may help new users understand how they don't have fragmentation, they have options.
