I didn't expect to run into this while recording.) 878 879 - Anyway, my favorite demo is this. 0 0 880 881 Watch me create a Bluesky post by creating a record via pdsls: 882 883 <Video src="./1.mp4" poster="./1-poster.jpg" muted playsInline controls /> 884 885 - This works with any AT app, there's nothing special about Bluesky. In fact, every AT app that cares to listen to events about the Bluesky Post lexicon knows that this post has been created. Apps live downstream from everybody's records. 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 886 887 A month ago, I've made a little app called [Sidetrail](https://sidetrail.app/) ([it's open source](https://tangled.org/danabra.mov/sidetrail)) to practice full-stack development. It lets you create step-by-step walkthroughs and "walk" those. Here you can see I'm deleting an `app.sidetrail.walk` record in pdsls, and the corresponding walk disappears from my Sidetrail "walking" tab: 888

This may not be the most efficient way to analyze social data, but if you squint, you might see a glimpse of a post-app future.
