journaling is not here to preserve data, but to preserve integrity. You would be pleased if the data were on disk, but the filesystem's got broken and unrepairable...
People need to know what journaling was introduced, and clearly it is not here to preserve your little settings you got smashed because you wanted to play World of Goo. Get serious.

If journaling is not for that, then I want something which is! And yes, I do want to play World of Goo!

Why should I give a damn about the filesystem structure except as a prerequisite to being able to
get to my files. I want my files, and that means file *content*. So I want a system which does a
reasonably reliably job of ensuring that content doesn't disappear. Ext3 is such a system. Maybe it
was unintentional at the time it was designed, but now that it's recognized as a good idea, let's
*keep* making systems that work as well as it!
