OP and Founder of Kyso here - we built Kyso to make it easier to blog your notebooks to the public and also to make them easier to share in teams. The linked post is actually a Jupyter notebook itself - analysing the number of notebooks on Github. A key element with Kyso is that the code is hidden by default to make it readable to non-technical people but you can click on the "code hidden" button on the top right to…
In my opinion hiding code is an anti feature as exposing the code by default gives you more incentive to write clean understandable and explaining (self documenting) code as it's always visible. By hiding it people might be more likely to paste in big blobs ugly code that would be much better put into a reusable function then in a notebook snippet.
Image you had a notebook to analyse sales data and you needed to present the results to your CEO (who perhaps cannot code) - this feature lets you present the notebook as is, without needing to prepare a report in some other format
