I think this looks great for CMS websites: where a user wishes to build an entire page in a web GUI. For composing text in blocks on existing pages, like comments or posts, you would need a lighter-weight solution. SlateJS (https://github.com/ianstormtaylor/slate https://github.com/ianstormtaylor/slate) fits that purpose for me exceedingly well, more than DraftJS, Quill and others, since it doesn't treat XML/HTML as a second-class citizen. The levels of complexity with text representation are: Document -> Post -> Text which corresponds roughly to the data sources: JSON/Data Structure -> XML/HTML -> Plaintext / Markdown Markdown can "upscale" to documents, but JSON data structures, by virtue of their complexity, do not "downscale" well at all to Markdown. HTML is the simple middle for me: it shouldn't be used for documents, but it is totally intuitive for posts where a users simply wants to adjust the color of one's text. The blocks wrapping this text should own the data structure, e.g. a flag for "NSFW Content" shouldn't be in the text editor but an option on the post itself.
