This is really exciting, although I think 'delivered' may be putting things a little strongly at the moment.
I've been running Elgg alongside moodle for the last term, and even as
seperate systems they complement each other beautifully. Integration of
the two will, I'm sure, produce a learning space greater than the sum
of its parts.
Immediately appealing are the ideas of being able to set journal /
assignment type activites in Moodle to be accomplished in Elgg, so that
learners can share their reflections with their peers rather than just
their teachers, and to bring Elgg's social tagging tools to Moodle
resources and activities
. Much as I love it, I don't think Moodle has
really sussed the whole metadata
tagging thing yet, and seeing this
happen in a socially constructed way makes far more sense than the
top-down vocabularies and taxonomies we're promised in the UK - have a
glance over at http://moodle.org/mod/forum/discuss.php?d=33044#154803
It's also going to be interesting to see how this compliments the blogging tools we're promised for Moodle 1.6.
Their abstraction layer model opens up other interesting possibilites, like perhaps even integration between Moodle, Elgg and open source school management information systems.
