Creating an ecourse is easy, keeping people interested and paying attention in that ecourse is a bit more involved.

When someone subscribes to your ecourse, they're looking for something from you. 

Maybe it's information.

Maybe it's advice.

Maybe they want to model what you're doing.

Maybe they just like you.

Whatever the reason, they subscribed to it for a reason.  Your job is to figure out what they want, right?  Your job is to create an ecourse for the people who will subscribe to it. 

This may be a bit difficult to understand when you're first starting out, but not as much as you might think.  If you follow my teachings, you should be creating an ecourse on stuff you already know.  Since you already know it, you should know what other people interested in that subject know as well, right? (that's just common sense) 

On the flip side, you should also understand what people are NOT interested in as well, right?

Understanding all that, when you create your ecourse, come from a position of someone who's interested in the subject, not someone who wants to TEACH on that subject.  Ask yourself, "When I first started out, what did I want to know about this?"  And then take that and run with it!

Now, after you've been doing this a while, you should have some sort of following.  If so, why not ask your followers what they want?  The simple way to do it is send out an email to everyone asking "Hey, what do you want to receive from me and how would you like it delivered?" 

I would also give your subscribers something when they answer.  Offer an audio or a short report for doing so.

The beauty is, you can have PLENTY of directions to go with ANY ecourse you create now.  AND, you already know people are interested because they have already told you they were!
