The other thing I could do in Node-RED is adding a location to a post even when it doesn't have one itself. This can be done because I keep track of locations with OwnTracks. Node-RED can add the location to the post.
Next I need to implement destinations for likes and bookmarks, to make it possible to automatically fetch information title even when micropub apps don't do it.
The next thing that I want is a special micropub endpoint that I can write posts to from Node RED where these posts will disappears after a few hours, days or when removed, an ephemeral feed.
