RE: The Secret Is Simplicity

Not a bad idea.

With my own onboarding "school" I make things simple. Read about account creation and keeping your keys safe, OK now create your account.

Now go make 10 comments on posts.

Now read about introduction posts and see some examples. Now write your own.

Etc

But, people have the ability to jump the gun and do stuff they aren't ready for. Having a front end that unlocks as you check off items would be the best training ground for strong bloggers.
