DEX: Debian and its derivatives, getting things done together « We'll see | Matt Zimmerman
I like that. There are a lot of different neat things in various derived projects. Ubuntu creates a lot of new things especially on the UI side (at least thats what I see from blog posts on the planet). So seeing all those changes go back to the root project is great. It's Open Source, as many people as possible should benefit from improvements made by individuals. There is no reason to duplicate effort here.
