what other filesystem?

That was my first thought also. Being from Austria/Europe, I just hear now 
that Reiser murdered, and I do not have any more information about that 
and also don't really care too much. Seems like they believe she's dead 
but nobody found her. But that's another story.

"Reiserfs is nearing the end of its run" is what strikes me. I've been 
using it for years, and had some very bad and nasty hardware issues that 
destroyed hard disk contents, but could get back most of the data on it.

The biggest issue was once a broken RAID controller decided to rebuild a 
RAID with the wrong disk. He thought the new empty disk was good and one 
existing disk was the spare disk, and rebuilt RAID-5 checksums. Which, 
obviously, simply destroyed whatever useful was there. That way, the first 
~20-30GB of the 500GB RAID contents were completely destroyed, including 
partition tables etc. With "reiserfck --rebuild-tree" I got most 
information back and that's why I stick to this filesystem. I know now how 
to get it back in case of problems, no matter how speedy other filesystems 
could be, that is the most interesting point for me.

Speed doesn't matter anymore once your data is gone.
