I'm writing on Substack now, because I really like the ecosystem at this point. But I'm also well aware that they could tank it like Medium did, or close up shop at any point. So I have a recurring task in my issue tracker to make a full backup. One of the reasons I'm willing to build on Substack at this point is because of the ability to dump the most meaningful data - subscribers and posts. That said, the dumped data is not in a format that can be just uploaded to a different platform, or to my own site. That's not an issue for me, because I can write a little code that will transform the posts exactly how I need them for upload to a different platform, or my own site. When I end up needing to do this, I'll probably add custom styling that will look better than Substack's anyway, particularly in reference to code blocks. I feel for nontechnical people. How do you decide where to invest your time? What do you do when the platform shifts in a bad direction, or closes entirely? AI tools will probably help a lot of people in this situation, if they were good about maintaining backups in the first place. I imagine "Can you convert my Substack archive to a format that will work on x_new_platform" would probably be a useful prompt.
