The Pitch-O-Matic
(draft) Presentations are just playlists!
NeoDecks are Mushrooms of The Big Fungus.
More practically, NeoDecks are playlists of composable, reusable Nuggets that live on individual wiki pages. Creating a NeoDeck means understanding Nuggetization, then plotting a course through Nuggets you want to include. Your presentation is the playlist you create.
To author a presentation, you'll quickly need a slide-sorter view that lets you see what is where, and also lets you grab subsets of your presentation and move them around.
This is one of several ATproto Apps we would love to see exist.
