You say that you'll be doing more media and learning oriented content than Wikipedia: how are you planning to support this - given how many contributors Wikipedia has? (And if you don't mind then maybe you could go deeper into how would you compare to Wikipedia. :)
In terms of numbers of contributors we believe Golden is at the stage where 1 hour editing on Golden produces more content/data than alternatives and the friction to edit is much lower. Are you looking for more depth on comparisons beyond the blog post?

In my experience as a Wikipedia editor, 80% of the time I spend writing an article is searching for (good) sources; 10% is editing friction like looking for the right infobox or the right model for what I want (although that time is reduced by experience); 10% is actually writing the article. Wikipedia’s contributing documentation discoverability is quite bad.
Your “high resolution” citations is a really great idea I wish WP would had. Does it support having multiple citations for the same part of the content? Overlaping parts?
If the goal is to build a learning plan, I find LearnAwesome's approach far simpler & better: No UGC except collecting links to existing resources on the Web, a simple markdown file and connections to other topics for discovery: https://github.com/learn-awesome/learn-awesome
Good luck!
