I noticed that Eliademy documents importing from Moodle, but we're all
interested in import and export, of course. ;-)

Sadly, proprietary systems like Fronter (owned by Pearson, but with Norwegian
origins and receiving a degree of favoritism) are widely used, although I did
notice that my former employer had chosen FutureLearn [1], which is also
proprietary as far as I can tell. Moodle doesn't seem to be that widely used,
and I can envisage pressure being applied to existing users to switch to
something proprietary that "everyone else is using".

What I've seen is that adopting "packaged" proprietary solutions is often
justified on cost-reduction grounds, but the IT budget and burden still
manages to increase. I guess I should summarise some of my observations in
blog form: it won't be very encouraging reading, though.
