Well, as far as I can tell, lots of Linux people are hipstery special little snowflakes and fork things because some small thing isn't exactly as they want it, and that's where most of the fragmentation comes from.
Assuming that's largely accurate, why would it not be a problem?
What if we had, say, three major Linux distros instead of dozens of half-assed ones? How many tinkerer-distros does the world need? -As many as it takes to prevent Linux from ever conquering the desktop, it seems.
But seriously.. Please stop.
