I'm not sure I understand what LMDE is anymore. I came to this distro looking for a true rolling release that would never need to be reinstalled, much like Arch, but without the pain of doing the bare-bones install. Reading up on wikipedia about rolling releases, I learned that since it's based on Debian Testing, LMDE is not fully a rolling release and should be considered cyclical instead. Problem is, wikipedia's function as my brain extension ends here because it has no article on cyclical releases, so I come to you with... questions!
(1) What's the difference, and how does it affect the 'will-never-have-to-reinstall' thing?
(2) LMDE is just a mintified gnome desktop, right? So when gnome 3 comes out (soon!), if I make the switch, I will not have LMDE anymore but just Debian Testing with gnome 3? This raises the question : what are the differences between lmde and plain debian testing?
