I would really love if this became an option, since I’m planning on making my own instance. I’d like to keep my subscriptions, posts, comments and bookmarks and migrating would be something great. What do you think?
That’s true but it’s equally true of all content you put on literally any website ever, so I figure I can choose to worry about that (in which case I guess you get into the world of exporting and scraping and backing up everything you ever contribute anywhere, which some people are really into and that’s fair!), or to not worry about that.
