I think that (4) is actually mixed with (1) as well.  The problem is
that the activity API is auto-saving work sessions.  If left unchecked
by the user they'll end up with a Journal full of lots of entries they
didn't intentionally create.  The system doesn't require the
intentionality of its user to save, yet the result of saving and
auto-saving are identical.  It's hard to find the important things among
the pile of unimportant things which result from everyday use of the
interface.  From a user's perspective, or the perspective of their
teacher, this is equivalent to data loss.

Additionally, users could be deleting their Journals from the command
line simply because they can't find anything they need and they don't
care about saving their data.

We have a data manager which doesn't acknowledge files, purportedly for
the benefit of its very young, and technically uninitiated users.  Then,
when it's not working they drop into the command line and delete its
configuration and data caches manually using rm -rf !  (This knowledge
is becoming quite common in at least one of our deployments.  Just
yesterday a kid from Uruguay came into #olpc-ayuda to ask exactly how to
do this.  And this morning a user spontaneously wrote rm
.sugar/default/confis into the channel...)

"Anything that can use a file" would be a good description of all the
main use cases.  How do we get lumps of bits from here to there without
acknowledging the utility of the file abstraction?

I think we should ask around on olpc-sur!  I also recommend coming to
#olpc-ayuda and talking with the kids who are trying to 'fix' issues
with their Journal via the command line.
