Jupyter Notebooks are great since you can have put your experimental data and share it in an interactive format. They have the potential of becoming the de facto standard for scientific collaboration. But what if you add a library where you can only load data from Azure ML Studio? then you cannot share your notebook anymore. Your notebook got tainted with proprietary stuff from a specific vendor... Science is about being able to universally reproduce experiments, and vendor lock-in prevents that. We already have enough problems in scientific publishing with journals. So if you like Jupyter, and you want it to become the standard science needs, avoid proprietary extensions. Let's not go back to share stuff in paper or its modern equivalent, PDFs.
