And that's how you learn...

Yeah  a FAFO Arch user probably makes his own mistakes more often than the packages are unstable. I have been known to dabble in the AUR.

You just get the latest version of an app when it hits stable on Arch

I agree with you but actually Arch Linux uses the latest stable versions of applications unless you install a newer one from the aur. 

In my view there are two types of Linux users - Git 'Er Dun (folks with serious mission critical uses) and F*** Around and Find Out (folks who use Linux as a hobby or for fun.) I have the utmost respect for GED folks using rolling release distros but I certainly understand the logic of stable point releases here. Personally I am a FAFO user so I run Arch or Debian Testing for personal use, and GED Linux Mint for visitors and family members. My worst example of FAFO is running Debian Testing with GNOME Extensions. It's a recipe for disaster, but you can learn a lot. I've found that Arch is more stable than the toxic cocktail of GNOME and Debian Testing.
