I think it's one of the most intuitive and easiest tools to use I've had the pleasure of using on any linux distro.

it's IMHO the only central system administration package for linux that actually does its job.
Mind, YaST used to be utter crap, but since YaST2, that is of the past. Nowadays I'm very happy with YaST2 and would suggest that other distros adapt YaST2 too.

YaST was actually coded long before Novell purchased SUSE. I'll say this, as far as system administrating goes, I still much prefer the command line...but when it comes to needing to make quick changes it truly is the best tool.

Although I think everyone should have CLI skills, it is true that more Linux distributions need a centralized administration point like YaST. It would help with the adoption as you don't require as much specific experience with Linux to utilize it.
