I found this morning that I cannot start a comment beneath a story that already does not have a comment. I am not sure know why this is the case. In general, I think Medium’s notes and responses are great structures in place.
A response is distinct from a note. A note is more of a personal comment. It is short enough to let the author know of specific comments. A response is a full post that stands on its own. Both have their strengths.
This “new” response writing system looks a little strange, and will take time to adjust. Even so, the responses catenate well. The first response is a stand-alone post. The next comments follow on the parent post. Interesting!
