If a program is developed for Linux, why exactly does it matter what distro you are using? How does installing programs like Steam/Dropbox/Skype work across distros like Mint, eOS, Debian, Fedora, etc.
On Steam's site for example it says:
Currently, Steam for Linux is only supported on Ubuntu 12.04 LTS or 12.10 with the Unity, Gnome, or KDE desktop. Additional distributions will be examined for support as time permits. For more information on Steam for Linux, see https://wiki.ubuntu.com/Valve
Do you really have to be running those DEs? Is it assumed that Ubuntu-based OSes like Mint, eOS would work fine? As well as the various Ubuntu flavors?
Or if you were running Ubuntu and downloaded the Fedora or opensuse download link on the Skype website would it simply not work?
