Hey HN, creator here! My goal is to build an app to capture personal knowledge over a lifetime. Hence data longevity is key. I’m looking forward to your thoughts, especially for my choice of using HTML instead of Markdown as file format. I debated this for a while. HTML has the advantage that can be previewed in any browser with formatting and images intact. Markdown would require a compatible app (text editor aside, which won’t show images). Also, HTML documents can easily be shared as single file, even if they contain embedded images. What do you think?
