To try and respond briefly, don't forget organizations that are using Debian. For a lot of organizations, it's neither practical nor safe to do a nightly upgrade on your hundreds of computers.
Also, don't forget that a lot of the reason "stable" is stable, is because it sits frozen for a while and thus problematic interactions *between* packages can be found and eliminated. If everything is changing all of the time, you can't do this nearly as well. I like releases! And I really like having separate "stable" and "unstable" lines being developed in parallel! Lex Spoon
