To be clear, I am only suggesting an additional way to discuss notebooks => If you have a question about a particular line/section of notebook, then choose hypothes.is, for all other purposes use forums?
Yes, I am not sure if hypothes.is will notify about new comments, I agree that would be valuable.
The problem with forum only approach is that, when I wonder about some aspect of the notebook, it is hard to find if any one else is in the same boat without reading over all the comments on that topic. This can lead to repeated questions too. Can you elaborate on how we can leverage gist ?
Having said that, I have only started using Hypothes.is since a couple of days and loving it so far. Not sure how well it works for a bigger group like this.
