> Do you think they are putting their focus on marketing over content?

I never said, nor meant to imply, judgements about any other projects. I was simply sharing the choices we've made based on our priorities and resources.

Personally I'm comfortable with those choices because they've resulted in literally hundreds (>650 at my last count) of nice looking and fun to use coding tutorials. I'm also quite proud of the authoring flow we built: these codelabs are generated directly from Google Docs (you don't have to write a line of code to produce them) and we've open sourced the tools for others to use (https://github.com/googlecodelabs/tools).
