I listened to Dave's podcast in which he starts to describe what he is doing with WordLand and FeedLand, and that sounds a lot like what I said that I want in practically my first post on micro.blog. Right now I am writing this using Drummer and it will be published to my Daynotes blog. If I want to also publish this on my micro.blog I need to copy and paste it in to another outline from which posts to micro.blog are published.

Copy and paste is a lot of work, what if for every post I could specify which publishing destination that post goes to simply by selecting the destination locations via a checkbox? What if I could later add a destination by simply going back to that post and checking another box, or clear a checkbox and it is removed. When I edit the item the changes are automatically re-published. BTW, the last item probably won't work to social network destinations because they generally don't allow editing.

The key is the per item control over the publishing destination and continual ability to edit the item. For now micro.blog's ability to cross post items I publish to it to Mastodon and Bluesky come closest to my vision, but that is not on a per post basis, it's all items published to my micro.blog that are published to those other destinations.
