The course is called MobiMOOC. I've never been in a MOOC before (this was the first time I'd even heard of the concept), and I feel a bit like I'm wandering around lost while drinking from the fire hose of mobile information.
From the first couple days, I can see there are several components to the course - the wiki (above), a mailing list (which is currently going nuts with introductions and initial mailings), people writing all over the place in their own personal blogs, and live classroom meetings. Fortunately, there's another short video about how to navigate MOOCs.
From the video, I clearly was correct that one component is posting thoughts and ideas in your own blog about the course (Step #2 of how to navigate: Declare a space) as part of having a space to engage with others about the course material. No reason to spin up an entirely new blog spot, so LiveJournal it is. I'll tag all MobiMOOC posts with their own tag so they can easily be sorted.
So in the spirit of the first week's questions, tools I use regularly (> 1/week) on my Droid Incredible (HTC):
And some cool tools that I use less often:
This is a bit older talk (2008) and a bit longer (~60 minutes), but it really feels to me like a MOOC is a variant of what Michael Wesch talks about in this lecture. It's a fantastic description of how people ought to learn and has a lot of applicable ideas outside the university setting (such as in my area of Technical Writing and Documentation).
