In light of the fact that most documentation people use to learn LaTeX is outdated or just wrong it would be a great advantage if we at TeX.SX had a community-driven reference.

A collection of simple examples with minimal boilerplate sounds like a great alternative to me and might succeed to convert people to follow the right path.
