Like only get the the audio from kind 1s, kind 1111s, etc... ?
👉 I don't get the use case for this.
Or apps build around the Audio track events (31337 and 31338) ?
Or apps like YakBak ?
👉 I again don't see the use case. Especially if you then promote new kinds like that to be included in text based Twitter clones.
Organizing everything per content type is silly to me anyway, so I don't get the question I think.
The audio app I do need is a long form one that can take in Articles, Pods, YouTube, ... and let me handle one queue for all of them combined. Let's me highlight in text when I open up my phone, let's me comment in text or voice, etc...
