This is a great idea for a regular thread! Thanks for posting.

I'm taking Computing for Data Analysis on Coursera, which is more or less an R primer. There's only one more week left in my session, so there's not much time left to study together, but regardless I'm open to studying with other LWers taking the course. So far it's pretty good, so I can recommend the course if you're thinking of taking it.

I probably won't have much time for MOOCing in the near future since next week I'm starting a new job that I expect to be intellectually demanding and I'll want to do other kinds of things in my free time. But you never know.

Edit to add: I'm also on Lesson 5 of Differential Equations on Udacity, but since it's not timed I've put it on the back burner. I'm planning to finish it up once the R course is done.
