It’s a non-starter for me because I sync my notes, and sometimes a subset of my notes, to multiple devices and multiple programs. For instance, I might use Obsidian, Vim and tasks.md to access the same repository, with all the documents synced between my desktop and server, and a subset synced to my phone. I also have various scripts to capture data from other sources and write it out as markdown files. Trying to sync all of this to a database that is then further synced around seems overly complicated to say the least, and would basically just be using Trillium as a file store, which I’ve already got.
I’ve also be burnt by various export/import systems either losing information or storing it in a incompatible way.
Let’s face it, it’s a countries leader(s) that decide to feed their population into a meat grinder, not the people themselves. At this point there may ne little the average Russian can do to stop the process, at least, without significant retribution from the same government.
