I've written/am writing openmoko-today2, openmoko-dates[1,2],
openmoko-worldclock2, openmoko-messages2 and libjana (the back-end
library for calendar/time/journal stuff).

As OpenMoko is based on GMAE, the best way to get experience in writing
apps would be to start off writing simple GTK apps (in my opinion)

As OpenMoko is based on GTK, all the GTK bindings potentially work - so
that's Python, Perl, Vala, Mono, Ruby, C++... You name it. The
openmoko-specific libraries still need bindings, however, but this would
be a very small job for anyone that knows how.

Unfortunately, there aren't many small demo apps :( As openmoko uses
evolution-data-server for PIM storage, any application that uses this is
a good example - this includes the core openmoko applications
(openmoko-contacts, openmoko-tasks, openmoko-dates), but also many apps
in GNOME/using GTK too. http://www.pimlico-project.org/ - These apps,
for example. Synchronisation is relatively unexplored, but if you're
interested in this, I'd suggest checking out Conduit, SyncEvolution or
OpenSync, whichever tickles your fancy.

Perhaps developers could be more vocal about what they're doing?
Certainly people are responsive to questions posted to this list. I
often blog about what I'm doing with OpenMoko on my site
( http://chrislord.net/ ) and I keep a TODO list on my user page
(ChrisLord) on the wiki, although I must admit, I've let the latter slip

I think your concerns are valid, I'm sure people would be pleased to
have someone helping with these kind of things (community issues and
