If that is all you do, it is fine.
The problem shows up when the journal is trashed. I am not sure
if Reiser is any better.
I was told that one advantage of ext3 over reiser is that you
can use ext2 tools to fix things. That is true if you shut it
down clean. It is not true after an unclean halt. You need to
let the ext3 journaling fix it first.
The same goes for mounting an ext3 as ext2. It works if you
shut it down clean. After an unclean halt, you can't, and
fsck.ext2 can't fix it. Again, let the ext3 journal fix it,
shut it down clean, then you can mount it as ext2.
In fairness, you can't mount a reiserfs as ext2, no matter what
you do. They don't claim you can.
