By that logic, there's no point in ever deleting anything online, so why even bother with hiding them? Just leave everything up there forever, whether the person who wrote it still wants it to be there or not.
Also, not everyone has the time, programming skills and resources to just fork a project, never mind run their own server. That's not a constructive approach to a "this feature ought to work better" discussion.
Mastodon has the same fatal flaw. They want to keep your history and relationships hostage so you can’t leave.
You can migrate your relationships to a new Mastodon server.
And while you can't directly transfer the history (the debate over how/whether to do this has gone on for literally years), you can export an archive you can keep locally, and there are tools out there to parse it and convert it to some other form (static website, whatever). Someone's probably written an importer by now, though I'd have to look.
The fact that other copies might be out there (assuming a crawler archived the particular page while a post was up) isn't a reason not to remove the copies you can control.
#Bookwyrm is a book review site like Goodreads
#WriteFreely is a blogging service, and Medium is actually working on Fediverse integration.
If you use a Nextcloud server, there's a good collection of apps (some official, some third-party) that work with it. The ones I use:
Nextcloud - main app, does authentication, file access, optional auto-upload photos Nextcloud Notes - kind of like Google Keep, but simpler. (IIRC Carnet is more like Keep, and also open) Nextcloud Talk - instant messaging, supposedly can do voice but I've never used it for that Nextcloud News - RSS reader that syncs your feeds and read/unread through your Nextcloud server
Plus these apps that aren't Nextcloud-specific, but work with it and other sync methods:
OpenTasks - ToDo list (needs Dav5x to sync) DAVx5 - Syncs contacts, calendars and to-do items between any CalDav, CardDav or WebDav servers and your Android system, so you can access them with any local contacts or calendar app. (For instance: K-9 Mail can use contacts from my Google account and my Nextcloud account, and Simple Calendar can do the same with my calendars.) Floccus - Bookmarks manager that can sync across multiple desktop browsers and the mobile app, using any of several sync options including Nextcloud
Yeah, it's made more for refining and confirming details than for adding entirely new objects.
When I want to add something that's not on the map yet, I either add a note in StreetComplete and come back to it later on my computer, or I add it using Vespucci. (I've been known to add items using Vespucci, then reload the data on StreetComplete so I can fill in details that aren't in the presets and that I can't remember how to tag manually!)
