Sure, as I said, there's a lot more detail than the blog posts alone cover - e.g. each tutorial begins with lots of background info, some from Emma's blog, some written for the course specifically and some from other stuff on the internet/further reading books. Then you have the course tutor (Debi Alper) and she's excellent. Depending on the exercise for the week, you will get a line by line, or even word by word, critical analysis of your work.
There's also an emphasis on critiquing each other's work within the group and I think I've learnt as much from that as I have the course content. I have to admit, I partly did it in the hope of getting an online writing group (I've not been able to find a good one myself) and I've been lucky in this respect as everyone's very focused and supportive.
You are taught how to edit, exactly what it says on the tin! And all the exercises relate to the novel you're working on, so if you're struggling say, with how much emphasis to give a particular character, or want to know if your plot and structure are working, you'll get lots of advice on these specific to your own book. Before the course, I found myself going onto forums or going on blogs and asking questions about specific issues and people can give advice, but if they don't know your book, the advice can only go so far.
There are other courses out there of course and if you've done more formal education in creative writing (degrees etc) it wouldn't be worth considering but I thought this one was great value for money personally.
