Someone decided to trash the one part of Windows that was usable? The file system is no longer usable. The registry is not usable. This program listing was one sane place but now it is all crapped up.
This is a great quote from Bill Gates about how hard it is to keep implementations of good ideas both usable and organized.
I can see how the Windows Registry started as a great idea. On Linux the /etc folder is the system configuration and could potentially be improved by placing all data into a database. Gnome is using something similar to Windows Registry called Gconf. Some people dislike Gconf because it is reminisent of Windows Registry but Gconf is a grand idea. The trick will be if open source can do a better job keeping the cruft out of Gconf and /etc.
