Unlike the output of our old editor, the output of a text editor built on ProseMirror can ultimately be rendered as a DOM tree, Markdown text or any other number of other formats that can express the concepts it encodes, making it very versatile and solving many of the problems we run into with our legacy text editor.
An interesting look at the text editor The New York Times developed. There are no plans to make it all open source, which is disappointing since it’s built upon the open source ProseMirror.
I imagine a lot of news organizations would find this kind of tool useful.
