That is an unfortunate, probably unavoidable, byproduct of the freedom that brought Linux on so many computers, platforms and users. Everyone can write a software, or fork an existing one, nobody enforces a standard for development or integration. I guess it's not easy to build a giant free community around a free software and keep consistency. It's a mess, and has been a necessary one when the aim was to spread Linux as much as possible, but now we're paying the consequences. (Which is why I believe the day Microsoft will reveal their Linux distro, bringing stability and unification behind a known brand, is the day all non technical die-hard users and more importantly most commercial entities that use Linux will abandon the usual distributions, essentially killing them.) Haiku however was born as a clone of a closed system, and only recently is seeing some media coverage; there's no guarantee that, should it one day reach Linux' level of popularity, the influx of developers , users, and demand for more software, won't create the same issues there as well.
