I'm not the OP, but I am also currently taking the FP101X Mooc with Erik Meijer. So far, I'm enjoying it tremendously. I've signed up for several moocs the past couple years, but have never been able to stick with any. This is the furthest I've been able to actually stay with it, which is probably indicative of something.

The lectures are basically laid out 1:1 with Hutton's Programming in Haskell book, so if you're familiar with that book, you're familiar with the way the course is structured. I find the actual experience of doing all the homework questions very helpful, even if so far nothing has been particularly difficult.

I'm also taking it to help flesh out my Haskell learning. I rather like it.

Be aware it starts out really slow then 50% in ratchets up the fun into "scare away the freshman" territory with monads. I have to say preexisting knowledge has been quite helpful.

About my only complaint is the amount of "which of these 9 implementations are valid" exercises. Although i've been cheating and using hspec to tdd my way through them.
