Good article!

IMHO, tutorial hell is done by

1. obsolete tutorials on the Internet (Google continues to point them)

2. "teachers" who do not master the subject they teach (it is so exciting to publish a tutorial!)

3. "teachers" who have mastered the subject but are poor at communicating

4. so many "the next big thing" to learn

5. our laziness (and lack of knowledge) in filtering the good among all the crap

There is only one way to learn something: by doing that.
