Yes, absolutely. I would echo @krytonika. While I've read the white paper and followed the obvious Steemians, the complexity, nuances and pitfalls that a new Steemer could face, unwittingly, might hamper the growth of the eco-system or decrease the quality of the content to a point where there is there is little value. That's along the general use case.

On the other side -programming/code:

• Updating the interface - how to
• Maybe some walk throughs on some of the core code - opening the curtain
• Examples of extending the blockchain to other systems
• Break the modules down into levels - Beginner, Intermediate, Hare Core :-)

• Commenting on posts (I don't think a lot of Steemians understand commenting - I struggle where to reply - top level, inline, to the last comment) curations rewards as well the 6 layer limit and such.

As for where... Youtube works, you can then embed them in an article transcript. I think that if you leverage the Steemit eco-system and then encourage us to resteem and share on our other social media to bring more into the steemit eoc-system.

I'm in the same boat as @krytonika, just in a week. Learning, learning and more learning and trying to contribute.
