Bleeding edge is for people that know what they are doing.
It should be but it is not usually used by those who know what there doing.
Usually it is installed by people of low technical knowledge who have High Expectations
As a Developer of many years I have had too many encounters with these Users who download and install Bleeding edge only to quest after the newest features. Most of these Users are not ready for the Bugs and they Scream the Loudest. As a result I have lost my taste for bleeding edge. Just plain tired of fixing code..backporting..Work Arounds..Testing..reporting Bugs..Researching..Posting..Exchanging How Tos..etc
....Look at Windows it is always released full of BUGS (the user base are the Beta Testers)
....How about the UBuntus? Always in a state of Flux..
Personally, I have been using Debian Squeeze since it was in Unstable stage and now that it is about to move on to Stable I intend to stick with the incarnation for quite a bit.
For me it is a Pleasure to Use a Distro like Salix...
Stable is Good!
