Throughout this piece Oppenheimer provides examples of notes he wrote which eventually made it into his written output in their entirety.

This has generally been uncommon in the literature, but is a great form of pedagogy. It's subtle, but it makes his examples and advice much stronger than others who write these sorts of essays.

Showing students examples of work and processes that they can imitate will fuel their imaginations and capabilities rather than stifle them.

Oded Shenkar's three step process for effective problem solving using imitation: - Step 1. Specify your problem and identify an analogous problem that has been successfully solved. - Step 2. Analyze why the solution was successful. - Step 3. Identify how your problem and circumstances differ from the example problem and figure out how to best and most appropriately adapt the original solution to the new context.

The last step may be the most difficult.

The IndieWeb broadly uses the idea of imitation to work on and solve a variety of different web design problems. By focusing on imitation they dramatically decrease the work and effort involved in building a website. The work involved in creating new innovative solutions even in their space has been much harder, but there, they imitate others in breaking the problems down into the smallest constituent parts and getting things working there.

Link this to the idea of "leading by example".

Link to "reinventing the wheel" -- the difficulty of innovation can be more clearly seen in the process of people reinventing the wheel for themselves when they might have simply imitated a more refined idea. Searching the state space of potential solutions can be an arduous task.

Link to "paving cow paths", which is a part of formalizing or crystalizing pre-tested solutions.

those who know the language, know where the mistake is, In other words, they can easily spot the mistake and no better than to repeat it themselves, but either are powerless or too lazy to actually fix it on SE.

and those who don't, think that it's the correct way to spell it. So those who should no better are inadvertently perpetuating the mistake and teaching others that it is an acceptable/correct usage.
