At this point, think about architectures. (Thanks heaven we're a little more on topic now ;)
Especially Debian tries to support many architectures, at least as good as resources provide.
Lennarts Operating System Troll (LOST) resulting in DLL (Distributor-Less Linux) woul probably remove support for the minor archs. The 'linux app' market places replacing Distributors won't take responsibility for such a difficult time-consuming task, and the developers themselves certainly won't do it either. I can't see any solution to this problem. The diversity of archs may simply vanish, in last consequence.
Well, Poettering probably sees this as as a pro.
Along the existing distribution framework, a great deal of community will vanish too.
But distributions are a place where concerned people meet and talk, and work collaboratively. It's also a good starting point for developer newcomers. And IMHO those 'superfluous' meetings about questions of whom to support, where to go, or ideals and ideas like freedom in general, are a core part of the whole thing.
